description
The TPS2074 and TPS2075 provide a complete
USB hub power solution by incorporating three
major functions: current-limited power switches
for four ports, a 3.3-V 100-mA regulator, and a
DP0 line control to signal attach/detach of the hub.
These devices are designed to meet bus-powered and self-powered hub requirements. These

detailed description
BP
The bus-powered supply input (BP) serves as the source for the internal 3.3-V LDO and for all logic functions
in the device. In bus-powered mode, BP also serves as the source for all the outputs (OUTx). If BP is below the
undervoltage threshold, all power switches will turn off and the LDO will be disabled. BP must be connected to
a voltage source in order for the device to operate.
SP
The self-powered supply input (SP) serves as the source for all the outputs (OUTx) in self-powered mode. The
enable logic for the SP switches requires that BP be connected to a voltage source.
OUT1, OUT2, OUT2, OUT4
OUTx are the outputs of the integrated power switches.
3.3V_OUT
The internal 3.3-V LDO output can be used to supply up to 100 mA current to low-power functions, such as hub
controllers.
DP0_RST
DP0_RST functions as a hub reset when a 1.5-kΩ resistor is connected between DP0_RST and the upstream
DP0 data line in a hub system. To provide a clean attach signal on DP0 data line, the DP0_RST output goes
low momentarily (because of the upstream pulldown resistor) to discharge any parasitic charge on the cable,
then goes to 3-state and finally outputs a high signal. The low and Hi-Z pulse widths are adjustable using a
capacitor between PG_DL Y and ground, and are approximately 50% of the power-good time delay. Detachment
is signaled by a Hi-Z on DP0_RST. Both DP0_RST and PG will transition high at the same time.
Power Good (PG)
The power good (PG) function serves as a reset for a USB hub controller. PG is asserted low when the output
voltage on the internal voltage regulator is below a fixed threshold. A time delay to ensure a stable output voltage
before PG goes high is adjustable using a small-value ceramic capacitor from PG_DLY to ground.
PG_DLY
PG_DL Y connects to an external capacitor to adjust the time delay for PG and DP0_RST . For USB applications,
a 0.1 µF capacitor is recommended, however, reference the USB hub controller data sheet to determine the
needed pulse width criteria.
BP_DIS
BP_DIS is used to enable or disable the autoswitching function between bus-powered mode and self-powered
mode. When BP_DIS is connected low and the voltage on SP is greater than the undervoltage-lockout (UVLO)
threshold, the device will switch to self-powered operation automatically; if the SP voltage falls lower than the
UVLO threshold, the device will switch to bus-powered operation. When BP_DIS is connected high, the
autoswitching function is disabled and the device will not autoswitch to bus-powered operation if the SP voltage
is below the UVLO threshold.
BPMODE

or BPMODE

mode. The logic state is set according to the voltages on BP, SP, and BP_DIS. For the TPS2074, BPMODE
outputs a low signal to indicate bus-powered mode or a high signal to indicate self-powered mode. For the
TPS2075, BPMODE outputs a high signal to indicate bus-powered mode or a low signal to indicate self-powered
mode. This output can be used to inform a USB hub controller to configure for bus-powered mode or
self-powered mode.
(TPS2074) or BPMODE (TPS2075) is an output that signals when the device is in bus-powered

APPLICATION INFORMATION
external capacitor requirements
A 0.1-µF ceramic bypass capacitor and a 10-µF bulk capacitor between BP and AGND, close to the device, are
recommended. Similarly , a 0.1-µF ceramic and a 68-µF bulk capacitor, from SP to AGND, and from VEXT to
AGND if an external 5-V LDO is required, are recommended because of much higher current in the self-powered
mode.
From each of the outputs (OUTx) to ground, a 33-µF or higher valued bulk capacitor is recommended when the
output load is heavy . This precaution reduces power-supply transients. Additionally, bypassing the outputs with
a 0.1-µF ceramic capacitor improves the immunity of the device to short-circuit transients.
An output capacitor connected between 3.3V_OUT and GND is required to stabilize the internal control loop.
The internal LDO is designed for a capacitor range of 4.7 µF to 33 µF with an ESR of 0.2 Ω to 10 Ω. Solid
tantalum-electrolytic, aluminum-electrolytic, and multilayer ceramic capacitors are all suitable.
Ceramic capacitors have different types of dielectric material, each exhibiting different temperature and voltage
variations. The most common types are X5R, X7R, Y5U, Z5U, and NPO. The NPO type ceramic capacitors are
generally the most stable over temperature. However, the X5R and X7R are also relatively stable over
temperature (with the X7R being the more stable of the two) and are therefore acceptable for use. The Y5U and
Z5U types provide high capacitance in a small geometry , but exhibit large variations over temperature. For this
reason, the Y5U and Z5U are not generally recommended.

APPLICATION INFORMATION
external capacitor requirements (continued)
A transient condition occurs because of a sudden increase in output current. The output capacitor reduces the
transient effect by providing the additional current needed by the load. Depending on the current demand at the
output, a voltage drop will occur across the internal resistance, ESR, of the capacitor. Using a low ESR capacitor
will help minimize this voltage drop. A larger capacitor will also reduce the voltage drop by supplying the current
demand for a longer time, versus that provided by a smaller capacitor.
overcurrent
An internal sense FET checks for overcurrent conditions. Unlike current-sense resistors, sense FETs do not
increase the series resistance of the current path. When an overcurrent condition is detected, the device
maintains a constant output current and reduces the output voltage accordingly. Complete shutdown occurs
only if the fault is present long enough to activate thermal limiting.
Three possible overload conditions can occur. In the first condition, the output has been shorted before the
device is enabled or before BP and SP have been applied. The TPS2074 and TPS2075 sense the short and
immediately switch into a constant-current output.
In the second condition, the short occurs while the device is enabled. At the instant the short occurs, very high
currents may flow for a very short time before the current-limit circuit can react. After the current-limit circuit has
tripped (reached the overcurrent trip threshold), the device switches into constant-current mode.
In the third condition, the load has been gradually increased beyond the recommended operating current. The
current is permitted to rise until the current-limit threshold is reached or until the thermal limit of the device is
exceeded. The TPS2074 and TPS2075 are capable of delivering current up to the current-limit threshold without
damaging the device. Once the threshold has been reached, the device switches into its constant-current mode.
OC response
The OCx output is asserted (active low) when an overcurrent or overtemperature condition is encountered and
will remain asserted until the overcurrent or overtemperature condition is removed. Connecting a heavy
capacitive load to an enabled device can cause momentary false overcurrent reporting from the inrush current
flowing through the device and charging the downstream capacitor. The TPS2074 and TPS2075 are designed
to reduce false overcurrent reporting by implementing an internal deglitch circuit. This circuit eliminates the need
for an external filter, which requires extra components. Also, using low-ESR electrolytic capacitors on the
outputs can reduce erroneous overcurrent reporting by providing a low-impedance energy source to lower the
inrush current flow through the device during hot-plug events. The OCx

power dissipation and junction temperature
The major source of power dissipation for the TPS2074 and TPS2075 comes from the internal voltage regulator
and the N-channel MOSFETs. Checking the power dissipation and junction temperature is always a good
design practice. Begin by determining the r
operating temperature. As an initial estimate, use the highest operating ambient temperature of interest and
read r
the power dissipation per switch can be calculated by:
Multiply this number by four to get the total power dissipation coming from the N-channel MOSFETs.
The power dissipation for the internal voltage regulator is calculated using:

thermal protection
Thermal protection prevents damage to the IC when heavy-overload or short-circuit faults are present for
extended periods. The faults force the TPS2074 and TPS2075 into constant-current mode at first, which causes
the voltage across the high-side switch to increase; under short-circuit conditions, the voltage across the switch
is equal to the input voltage. The increased dissipation causes the junction temperature to rise to high levels.
The protection circuit senses the junction temperature of the switch and shuts it off. Hysteresis is built into the
thermal sense circuit, and after the device has cooled approximately 20 degrees the switch turns back on. The
switch continues to cycle in this manner until the load fault or input power is removed.
The TPS2074 and TPS2075 implement a dual thermal trip to allow fully independent operation of the power
distribution switches. In an overcurrent or short-circuit condition the junction temperature rises. Once the die
temperature rises to approximately 140°C, the internal thermal-sense circuitry determines which power switch
is in an overcurrent condition and turns only that power switch off, thus isolating the fault without interrupting
operation of the adjacent power switch. If the die temperature exceeds the first thermal trip point of 140°C and
reaches 150°C, the device turns off. The OC
overcurrent occurs.

undervoltage lockout (UVLO)
An undervoltage lockout ensures that the device (LDO and switches) is in the off state at power up. The UVLO
will also keep the device from being turned on until the power supply has reached the start threshold (see
undervoltage lockout table), even if the switches are enabled. The UVLO will activate whenever the input
voltage falls below the stop threshold as defined in the undervoltage lockout table. This facilitates the design
of hot-insertion systems where it is not possible to turn off the power switches before input power is removed.
Upon reinsertion, the power switches will be turned on with a controlled rise time to reduce EMI and voltage
overshoots.
self-power to bus-power or bus-power to self-power transition
An autoswitching function between bus-powered mode and self-powered mode is a feature of the TPS2074 and
TPS2075. When this feature is enabled (BP_DIS is inactive) and SP is removed or applied, a transition will be
initiated. The transition sequence begins with the internal LDO being turned off and its external capacitance
discharged. Any enabled switches are also turned off and the external capacitors discharged. Once the LDO
and switch outputs are low, the internal logic will turn the LDO back on. This entire sequence occurs whenever
power to the SP input is removed or applied, regardless of the source of power, i.e., an external power supply
or the use of the external regulator.
universal serial bus (USB) applications
The universal serial bus (USB 1.1) interface is a 12-Mb/s, 1.5-Mb/s, or 480 Mb/s (USB 2.0), multiplexed serial
bus designed for low-to-medium bandwidth PC peripherals (e.g., keyboards, printers, scanners, and mice). The
four-wire USB interface is conceived for dynamic attach-detach (hot plug-unplug) of peripherals. Two lines are
provided for differential data, and two lines are provided for 5-V power distribution.
USB data is a 3.3-V-level signal, but power is distributed at 5 V to allow for voltage drops in cases where power
is distributed through more than one hub or across long cables. Each function must provide its own regulated
3.3 V from the 5-V input or its own internal power supply.
The USB specification defines the following five classes of devices, each differentiated by power-consumption
requirements:
D
Hosts/self-powered hubs (SPH)
D
Bus-powered hubs (BPH)
D

APPLICATION INFORMATION
USB power-distribution requirements
USB can be implemented in several ways, and, regardless of the type of USB device being developed, several
power-distribution features must be implemented.
D
Hosts/self-powered hubs must:
– Current-limit downstream ports
– Report overcurrent conditions on USB V
– Output 5.25 V to 4.75 at 500 mA
D
Bus-powered hubs must:
– Enable/disable power to downstream ports
– Power up at <100 mA
– Limit inrush current (<44 Ω and 10 µF)
– Output 5.25 V to 4.4 at 100 mA
– Not send power back upstream
D
Functions must:
BUS
– Limit inrush currents
– Power up at <100 mA
– Not send power back upstream (SP functions)
The feature set of the TPS2074 and TPS2075 allows them to meet each of these requirements. The integrated
current-limiting and overcurrent reporting is required by hosts and self-powered hubs. The logic-level enable
and controlled rise times meet the needs of both input and output ports on hubs, as well as the input ports for
bus-powered functions
USB hybrid hub
A USB hybrid hub can be simply implemented using the TPS2075 USB power controller and a TUSB2046 USB
hub controller as shown in Figure 33. The TPS2075 USB power controller provides all the power needs to the
four downstream ports and meets all the USB power specifications for both self-powered hubs and bus-powered
hubs. The power controllers integrated 3.3-V LDO is used to provide power for the hub controller and any other
local functions (e.g. transient suppressor SN75240 ), which saves board space and cost. The TPS2075 also
provides the hub controller with a power good (PG) signal that connects to the RESET
to automatically reinitialize the hub when switching between self-powered mode and bus-powered mode
whenever the self-power supply is connected or disconnected. The amount of time in which the hub controller
is kept in a reset state is controlled by a capacitor connected between the PG_DL Y pin of the power controller
and ground.
