The TPS22924BYZR is a single-channel, high-side load switch from TI's TPS22924 family. The N-channel MOSFET output is configured as a high-side switch with a 1:1 input-to-output ratio, so the pass element sits between the supply and the load with no series dropout beyond the Rds(on) drop.
Load voltage range and sequencing features
No separate Vcc/Vdd bias supply is needed — the switch is self-powered from the load rail. The integrated load-discharge feature pulls the output to ground when the switch is off, preventing the load from floating. Slew-rate control limits inrush current during turn-on, which avoids drooping the upstream supply rail when a capacitive load is connected.
Housed in a 6-pin DSBGA (6-XFBGA) package, the TPS22924BYZR measures roughly 1.2 mm × 0.8 mm — a footprint suited for space-constrained PCBs in handheld and IoT designs.
The base product number TPS22924 covers several Rds(on) and current variants; the BYZR suffix identifies this specific 2 A, 18.3 mOhm option in the DSBGA package.
