37 mOhm load switch for 1.05–5.5 V rails
The TPS22915CYFPT is a single-channel, high-side N-channel load switch from Texas Instruments, designed for general-purpose power-rail switching. Its 37 mOhm typical on-resistance keeps conduction loss low at the rated 2 A continuous output, making it suitable for battery-powered and low-voltage core rails where every millivolt of drop counts. The load voltage range spans 1.05 V to 5.5 V, covering 1.2 V, 1.8 V, 3.3 V, and 5 V rails common in portable electronics, IoT modules, and embedded systems.
Slew rate control and load discharge
Built-in slew rate controlled turn-on limits inrush current, preventing supply droop on upstream regulators when the load is connected. The integrated load discharge pulls the output to ground when the switch is disabled, eliminating floating output that could bias downstream logic.
Industrial temperature grade and DSBGA package
The 4-DSBGA package measures roughly 0.8 mm × 0.8 mm, a footprint that suits space-constrained designs but requires careful PCB layout for thermal and solder-joint reliability.
