GR7022

GR · Supervisor And Reset ICs · SOT-23

GR7022 from GR, 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 OUT output Chip output terminal; the datasheet limits the output voltage to GND-0.3 V to VDD+0.3 V (absolute maximum), and the output sink current IOL is at least 0.5 mA (typ. 1 mA) at VDD = 2 V with VOUT = 0.2 V.
2 GND power_in Chip ground terminal.
3 VDD power_in Chip supply input; operating voltage is 1.5 V to 12 V, with an absolute maximum input voltage of 15 V.
