MAX809RDBZRG 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; the datasheet gives no separate voltage or current limit for this pin. |
| 2 | RESET | output | Reset output (复位输出端); VOL is at most 0.3 V with 1.2 mA sink at VCC=Vthmin, VOH is at least 0.8×VCC with 500 µA source at VCC>Vthmax, and VRESET is limited to -0.3 V to VCC+0.3 V. |
| 3 | VCC | power_in | Chip supply input with an operating voltage of 1.0 V to 6.0 V and an absolute maximum input voltage of 6.5 V. |
