The TPS22914BYFPT is a single-channel, high-side N-channel MOSFET load switch from Texas Instruments. It switches load voltages from 1.05 V to 5.5 V and delivers up to 2 A continuous output. The typical on-resistance is 37 mOhm. The switch is self-biased from the load voltage — no separate Vcc/Vdd supply is required. The ON/OFF interface is non-inverting: a logic high on the ON pin turns the switch on; a logic low turns it off.
Slew-rate controlled turn-on limits inrush
The slew-rate controlled turn-on ramps the output voltage gradually, limiting inrush current into capacitive loads. This prevents upstream voltage droop on shared power rails — particularly useful when the load switch enables a bank of decoupling capacitors or a downstream regulator. No external soft-start capacitor is needed. The switch is a general-purpose type with a 1:1 input-to-output ratio. The output configuration is high-side, meaning the load is connected between the output pin and ground. The output type is N-channel, so the switch conducts when the gate is driven above the source voltage.
