HG809RM3-2.63

HGSEMI · Supervisor and Reset ICs · SOT-23

HG809RM3-2.63 from HGSEMI, 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 GND power_in Chip ground reference (0V). Connect to system ground.
2 RESET output Active-low reset output (RESET with overbar). Asserts low when VCC drops below the reset threshold Vth=2.63V (typical, ±2.5%). VOL <= 0.3V at ISINK=1.2mA; VOH >= 0.8*VCC at ISOURCE=500uA. Reset delay Trp is 80-350ms (typical 200ms) after VCC returns above threshold.
3 VCC power_in Chip supply input. Operating range 1.0V to 6.0V, absolute maximum 6.5V. Also the monitored voltage rail. Typical quiescent current 5.5uA @ VCC=6V, no load.
