Product details

High-side load switch for 5 A rails

It switches a 2.5 V to 5.7 V supply rail with a typical on-resistance of 14 mOhm, keeping conduction losses low enough that a 10-WSON package with exposed pad handles the thermal budget without airflow. The switch is self-powered — no separate Vcc/Vdd bias rail needed. On/Off control is non-inverting, and the part integrates Auto Restart, Load Discharge, Power Good flag, and Slew Rate Controlled turn-on. These features make it a fit for sequencing multiple power domains in a system — the Power Good output can gate downstream converters, and the controlled slew rate limits inrush into capacitive loads.

Protection and temperature range

Built-in fault protection covers over-temperature shutdown and under-voltage lockout (UVLO).

Supplied in a 10-WSON (3 mm x 2 mm body) with exposed pad, surface-mount only.

Frequently asked questions

What is the typical Rds(on) of TPS22954DQCR?

The typical on-resistance is 14 mOhm, which keeps conduction losses under 0.35 W at 5 A — manageable in the 10-WSON package with proper PCB thermal design.

What are the alternatives to TPS22954DQCR?

Within the same family, the TPS22953 is a similar 5 A load switch but without the Auto Restart feature. The pinout and package are the same, so it can be evaluated as a drop-in if Auto Restart is not required.

How to use TPS22954DQCR in a power sequencing application?

The Power Good output (PG) asserts when the output voltage rises above a threshold, making it suitable to enable a downstream regulator. The Slew Rate Controlled turn-on limits inrush; the external CT pin sets the slew rate. For sequencing multiple rails, connect PG of one TPS22954DQCR to the ON pin of the next.
