RT9818C-29GV

Richtek Tech · Supervisor and Reset ICs · SOT-23

RT9818C-29GV from Richtek Tech, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RESET output Active-low open-drain reset output (N-channel MOSFET to GND). Asserts low whenever VDD falls below the internal 2.9 V threshold and remains asserted for a 220 ms delay after VDD recovers above VTH. Requires an external pull-up (e.g. 100 kΩ to VDD); VOL < 0.4 V at ISINK > 3.5 mA.
2 GND power_in Ground reference for the device.
3 VDD power_in Supply/monitor input. Operating range 0.9 V to 6 V (absolute max -0.3 V to 6 V). Also the voltage sensed against the internal 2.9 V reset threshold (VTH tolerance ±1.5%).
