TPAX809TS3

TECH PUBLIC · Supervisor and Reset ICs · SOT-23

TPAX809TS3 from TECH PUBLIC, in a SOT-23. 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 pin (接地脚). All voltages are referenced to this pin.
2 RESET output Push-pull reset signal output. Driven low when VDD falls below the reset threshold (VRST = 3.08 V for TS3). Returns high at least 140 ms after VDD rises back above the threshold. Output drive: VOL ≤ 0.3 V at 3.2 mA sink (VDD=3V); VOH ≥ VDD-0.4 V at 1.2 mA source (VDD=3V). Max output current 20 mA.
3 VDD power_in Chip supply voltage and monitored input (芯片供电电源及待检测电压输入脚). Operating range 1.0 V to 5.5 V; typical IDD 10 µA at 3.0 V. Max VDD input current 20 mA; max slew rate 100 V/s.
