What are the key features of the TPS22945?

Key features include a 100mA current limit, auto-restart functionality, thermal shutdown, undervoltage lockout, and a low shutdown current of less than 1uA.

What is the auto-restart feature?

If an overcurrent condition persists beyond the 10ms blanking time, the device shuts off and attempts to restart after 80ms, provided the ON pin remains active.

What should be considered for layout?

Traces should be kept short, and ceramic bypass capacitors (1uF for VIN, 0.1uF for VOUT) should be placed as close to the device terminals as possible.

What is the pinout of TPS22945DCKR?

Use the TPS22945DCKR datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about TPS22945DCKR pinout to locate pins, power rails, and interface signals before layout.
