CAT811RTBI-GT3-HXY

HXY MOSFET · Supervisor And Reset ICs · SOT-143

CAT811RTBI-GT3-HXY from HXY MOSFET, in a SOT-143. 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 GND power_in Ground reference pin for the device.
2 RESET output Push-pull output that is pulled low when VIN is below the detect level and pushed high when VIN is above the detect level for 240ms.
3 MR input Manual reset input with logic thresholds of VIH at 0.7xVIN minimum and VIL at 0.3xVIN maximum.
4 VIN power_in Power input and the voltage node to be monitored, with an input voltage range of 1 to 6 V.
