Product details

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.

Frequently asked questions

Is TPS22920LYZPR compatible with 1.8 V logic levels?

Yes. The load-voltage range is 0.75 V to 3.6 V, which covers 1.8 V and 3.3 V rails. The On/Off input is non-inverting and does not require a separate Vcc supply, so the enable signal can be driven directly by a 1.8 V GPIO without level shifting.

What is the maximum current rating for TPS22920LYZPR?

The maximum continuous output current is 4 A. The 5.3 mOhm typical Rds(on) at 25°C sets the conduction loss floor; actual current capability depends on PCB copper area, ambient temperature, and the derating curve in the datasheet.
