The TPS22932BYFPT is a single-channel, high-side P-channel MOSFET load switch from Texas Instruments, designed for general-purpose power gating in low-voltage systems. It switches a load rail from 1.1 V up to 3.6 V and delivers up to 500 mA continuous output. Typical on-resistance is 55 mOhm, which keeps the voltage drop across the switch under 30 mV at 500 mA — negligible for most 1.2 V or 3.3 V rails. The part integrates a slew-rate-controlled turn-on to limit inrush current into capacitive loads, plus an active load-discharge path that pulls the output to ground when the switch is off, preventing floating nodes on the downstream circuitry.
Package, temperature grade, and board-fit
Housed in a 6-pin DSBGA (6-XFBGA) package, the part occupies roughly 1.2 mm × 0.8 mm on the board — a footprint suited for space-constrained portable and wearable designs. The DSBGA package requires careful PCB layout: the small solder balls (0.4 mm pitch typical for this family) demand a solder-mask-defined pad and a stencil aperture matched to the ball diameter.
Texas Instruments continues to manufacture this device with no announced end-of-life.
