Active production — 200 mOhm load switch with reverse current block
The TPS22916CYFPR is an active-production Texas Instruments load switch built around a P-channel MOSFET with a typical on-resistance of 200 mOhm. The switch is non-inverting and configured as a high-side, single-output device with a 1:1 input-to-output ratio. What sets this part apart in a small 4-pin DSBGA package is the integrated reverse current protection. If the output voltage rises above the input — from a charged capacitor bank or a back-feeding peripheral — the switch blocks the reverse current path, protecting the upstream supply rail. This is a feature typically found in larger or more expensive load switches.
