description

The TPS203x family of power distribution switches is intended for applications where heavy capacitive loads
and short circuits are likely to be encountered. These devices are 50-mΩ N-channel MOSFET high-side power
switches. The switch is controlled by a logic enable compatible with 5-V logic and 3-V logic. Gate drive is
provided by an internal charge pump designed to control the power-switch rise times and fall times to minimize
current surges during switching. The charge pump requires no external components and allows operation from
supplies as low as 2.7 V.

When the output load exceeds the current-limit threshold or a short is present, the TPS203x limits the output
current to a safe level by switching into a constant-current mode, pulling the overcurrent (OC

) logic output low.
When continuous heavy overloads and short circuits increase the power dissipation in the switch, causing the
junction temperature to rise, a thermal protection circuit shuts off the switch to prevent damage. Recovery from
a thermal shutdown is automatic once the device has cooled sufficiently. Internal circuitry ensures the switch
remains off until valid input voltage is present.

The TPS203x devices differ only in short-circuit current threshold. The TPS2030 limits at 0.3-A load, the
TPS2031 at 0.9-A load, the TPS2032 at 1.5-A load, the TPS2033 at 2.2-A load, and the TPS2034 at 3-A load
(see Available Options). The TPS203x is available in an 8-pin small-outline integrated-circuit (SOIC) package
and in an 8-pin dual-in-line (DIP) package and operates over a junction temperature range of –40°C to 125°C.

detailed description

power switch

The power switch is an N-channel MOSFET with a maximum on-state resistance of 50 mΩ (V

I(IN)

= 5 V).
Configured as a high-side switch, the power switch prevents current flow from OUT to IN and IN to OUT when
disabled.

charge pump

An internal charge pump supplies power to the driver circuit and provides the necessary voltage to pull the gate
of the MOSFET above the source. The charge pump operates from input voltages as low as 2.7 V and requires
very little supply current.

driver

The driver controls the gate voltage of the power switch. T o limit large current surges and reduce the associated
electromagnetic interference (EMI) produced, the driver incorporates circuitry that controls the rise times and
fall times of the output voltage. The rise and fall times are typically in the 2-ms to 9-ms range.

enable (EN)

The logic enable disables the power switch, the bias for the charge pump, driver, and other circuitry to reduce
the supply current to less than 10 µA when a logic low is present on EN . A logic high input on EN restores bias
to the drive and control circuits and turns the power on. The enable input is compatible with both TTL and CMOS
logic levels.

overcurrent (OC

)

The OC open drain output is asserted (active low) when an overcurrent or overtemperature condition is
encountered. The output will remain asserted until the overcurrent or overtemperature condition is removed.

current sense

A sense FET monitors the current supplied to the load. The sense FET measures current more efficiently than
conventional resistance methods. When an overload or short circuit is encountered, the current-sense circuitry
sends a control signal to the driver. The driver, in turn, reduces the gate voltage and drives the power FET into
its saturation region, which switches the output into a constant current mode and holds the current constant
while varying the voltage on the load.

thermal sense

An internal thermal-sense circuit shuts off the power switch when the junction temperature rises to
approximately 140°C. Hysteresis is built into the thermal sense circuit. After the device has cooled
approximately 20°C, the switch turns back on. The switch continues to cycle off and on until the fault is removed.

undervoltage lockout

A voltage sense circuit monitors the input voltage. When the input voltage is below approximately 2 V , a control
signal turns off the power switch.
