MAX809T-HXY

HXY MOSFET · Supervisor And Reset ICs · SOT-23

MAX809T-HXY from HXY MOSFET, in a SOT-23. 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 Chip ground terminal of the supervisor (datasheet pin table: 芯片接地端).
2 RESET output Reset output; VOL is at most 0.3 V at 1.2 mA sink when VCC is at Vthmin, and VOH is at least 0.8×VCC at 500 µA source when VCC is above Vthmax.
3 VCC power_in Supply/monitored voltage input; operating range is 1.0 V to 6.0 V, with a 6.5 V absolute maximum input voltage.
