5.3 mOhm load switch for 0.75 V–3.6 V rails
The TPS22920LYZPR is a single-channel, high-side N-channel load switch from Texas Instruments with a typical on-resistance of 5.3 mOhm. It handles a continuous output current up to 4 A across a load-voltage range of 0.75 V to 3.6 V.
The 8-DSBGA package measures 1.9x0.9 mm — a 0.4 mm pitch BGA that requires micro-via fan-out and a controlled reflow profile. Not a hand-solderable package; rework demands hot-air with a fine nozzle.
Buyers can commit to the BOM line without near-term obsolescence risk.
Built-in load discharge and slew-rate control
Integrated features include load discharge and slew-rate controlled turn-on, which reduce inrush current and prevent output-voltage overshoot during enable. The interface is a single On/Off pin with non-inverting input logic. The 1:1 input-to-output ratio means the switch passes the input rail directly to the load when enabled.
