MAXIM MAX14531E, MAX14534E Technical data

General Description

The MAX14531E–MAX14534E high ESD-protected
DP3T switches multiplex Hi-Speed (480 Mbps) USB
signals, low/full-speed USB signals, and analog sig­nals such as AC-coupled audio or video through any
of three channels. These devices combine the low on­capacitance (C

ON

) and low on-resistance (RON) nec­essary for high-performance switching applications in
portable electronics, and include an internal negative
supply to pass AC-coupled audio signals that swing
below ground (down to -2.0V). The MAX14531E–
MAX14534E operate from a +2.7V to +5.5V supply.

The MAX14531E–MAX14534E have a shutdown func­tion to reduce supply current and set all channels to
high impedance. The MAX14531E–MAX14534E feature
a VBUS detection function through the CB0 input to
automatically switch to the default USB signal path
upon detection of a valid VBUS signal. The
MAX14532E/MAX14534E feature internal shunt resis­tors on audio channels to reduce clicks and pops
heard at the output.

The MAX14531E–MAX14534E are available in a space­saving, 12-bump, 1.5mm x 2.0mm WLP package and
operate over the -40°C to +85°C temperature range.

ELECTRICAL CHARACTERISTICS

(VCC= +2.7V to +5.5V, TA= -40°C to +85°C, unless otherwise noted. Typical values are at VCC= +3.0V, TA= +25°C, unless other­wise noted.) (Note 2)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-

layer board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial

USB 2.0 Hi-Speed and Audio Switches with
Negative Signal Capability and ±15kV ESD

10 ______________________________________________________________________________________

Detailed Description

The MAX14531E–MAX14534E are high ESD-protected
single DP3T switches that operate from a +2.7V to +5.5V
supply and are designed to multiplex USB 2.0 Hi-Speed
signals and AC-coupled analog signals. These switches
combine the low on-capacitance (CON) and low on-resis­tance (R

ON

) necessary for high-performance switching
applications. These devices also meet the requirements
for USB low-speed and full-speed signaling. The nega­tive signal capability of all three channels allows signals
below ground to pass through without distortion.

Analog Signal Levels

The MAX14531E–MAX14534E are bidirectional, allow­ing UAX_, UAY_, UAZ_, and COM_ to be configured as
either inputs or outputs. Note that UAX_, UAY_, and
UAZ_ are only protected against ESD up to ±2kV
(Human Body Model) and may require additional ESD
protection if used as outputs. These devices feature a
charge pump that generates a negative supply to allow
analog signals as low as -2.0V applied to UAX_, UAY_,
UAZ_, or COM_. The negative charge pump is only
active when the part is enabled (CB0 or CB1 = 1).
Connect negative signals to UAX_, UAY_, UAZ_, or
COM_ only when the device is enabled.

VBUS Detection

The MAX14531E–MAX14534E feature a VBUS detec­tion input (CB0) that connects COM_ to UAX_ when
V

CB0

exceeds the VBUS detection threshold (V

VBDET

)

(see the

Functional Diagram/Truth Table

). Note that the
MAX14531E requires an external pulldown resistor
when using this function.

Digital Control Inputs

The MAX14531E–MAX14534E provide control logic
inputs, CB0 and CB1, to control the switch position as
shown in the

Functional Diagram/Truth Table

. Drive

CB_ rail-to-rail to minimize power consumption.

Shutdown Mode

The MAX14531E–MAX14534E feature a shutdown
mode to reduce the supply current to less than 1µA and
place the switches in high impedance. Drive both CB0
and CB1 low to place the devices in shutdown mode
(see the

Functional Diagram/Truth Table

.)

Click-and-Pop Suppression

The switched 100Ω shunt resistors on the MAX14532E/
MAX14534E automatically discharge any capacitance
at the UAZ_ (MAX14532E) or UAY_ and UAZ_
(MAX14534E) inputs when they are unconnected from
COM_ (see the

Functional Diagram/Truth Table

). This
reduces audio click-and-pop sounds that may occur
when switching to audio sources.

Applications Information

Extended ESD Protection

ESD-protection structures are incorporated on all pins
to protect against electrostatic discharges up to ±2kV
(Human Body Model) encountered during handling and
assembly. COM1 and COM2 are further protected
against ESD up to ±15kV (Human Body Model) without
damage. The ESD structures withstand high ESD both
in normal operation and when the device is powered
down. After an ESD event, the MAX14531E–
MAX14534E continue to function without latchup.

ESD Test Conditions

ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents
test setup, test methodology, and test results.

Human Body Model

Figure 4 shows the Human Body Model, and Figure 5
shows the current waveform it generates when discharged
into a low impedance. This model consists of a 100pF
capacitor charged to the ESD voltage of interest that is
then discharged into the device through a 1.5kΩ resistor.

Layout

USB Hi-Speed requires careful PCB layout with 45Ω
single-ended/90Ω differential controlled impedance
matched traces of equal lengths. Ensure that bypass
capacitors are as close as possible to the device. Use
large ground planes where possible.

Power-Supply Sequencing

Caution: Do not exceed the absolute maximum rat­ings because stresses beyond the listed ratings
may cause permanent damage to the device.

Proper power-supply sequencing is recommended for
all devices. Apply VCCbefore applying analog signals,
especially if the analog signal is not current limited.
