TC1232EOA713

Microchip Tech · Monitors & Reset Circuits · SOIC-8

TC1232EOA713 from Microchip Tech, in a SOIC-8. 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 PB RST input Push button reset input that ignores pulses shorter than 1 ms, recognizes pulses of 20 ms or greater, and forces both reset outputs active while driven low.
2 TD input Time delay input that sets the watchdog time-out to 150 ms with TD at GND, 600 ms when open, and 1.2 s when tied to VCC.
3 TOL input Tolerance input that sets the VCC trip point to 4.75V (5% tolerance) when tied to GND and 4.5V (10% tolerance) when tied to VCC.
4 GND power_in The ground reference for the device.
5 RST output Push-pull active-high reset output that goes high if VCC falls below the selected threshold, PB RST is forced low, the ST input is not strobed within the time-out period, or during power-up.
6 RST output Open-drain active-low reset output that goes low under the same conditions as RST (VCC below threshold, PB RST forced low, missed ST strobe, or power-up).
7 ST input Watchdog strobe input in which each falling edge resets the watchdog timer counter; a time-out forces the reset outputs active for at least 250 ms.
8 VCC power_in The positive supply (+5V nominal) for the device, specified for an operating voltage of 4.0V to 5.5V.
