# MAX809TDBZRG

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

MAX809TDBZRG from HANSCHIP semiconductor, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference for the supervisor. Connect to system ground. |
| 2 | RESET | output | Active-low reset output (RESET-bar). Asserted low while VCC is below the reset threshold Vth (3.08 V nominal for MAX809T) and held low for the reset timeout period (Trp, 80-350 ms) after VCC rises above Vth. VOL = 0.3 V max at ISINK = 1.2 mA; VOH >= 0.8*VCC at ISOURCE = 500 uA. |
| 3 | VCC | power_in | Supply input and monitored voltage. Operating range 1.0 V to 6.0 V (absolute max 6.5 V). The device compares VCC to the internal threshold Vth to generate the RESET output. Quiescent current ICC ~5.5 uA at VCC = 6 V. |
