TPS22942DCKR

Texas Instruments · Power Distribution Switches · SC-70-5

TPS22942DCKR from Texas Instruments, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT output Switch output; place ceramic bypass capacitor(s) between this terminal and GND.
2 GND power_in Ground reference for the device; place bypass capacitors between VIN or VOUT and this terminal.
3 OC output Active-low, open-drain over-current flag that indicates an over current, supply undervoltage, or over temperature state.
4 ON input Switch control input that must not be left floating.
5 VIN power_in Switch input; place ceramic bypass capacitor(s) between this terminal and GND.
