**HANSCHIP semiconductor** · Supervisor And Reset ICs · SOT-23-3

MAX809SDBZRG from HANSCHIP semiconductor, in a SOT-23-3. 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 (芯片接地端); the datasheet gives no additional electrical limits for this pin. |
| 2 | RESET | output | Reset output (复位输出端) that drives low (VOL max 0.3 V at ISINK = 1.2 mA with VCC = Vthmin) and high (VOH min 0.8VCC at ISOURCE = 500 uA with VCC > Vthmax), with VRESET limited to -0.3 V to VCC+0.3 V. |
| 3 | VCC | power_in | Supply input (芯片输入端) with an operating range of 1.0 V to 6.0 V and an absolute maximum of 6.5 V. |
