Microchip Tech · Monitors & Reset Circuits · SOT-23A-3

TC54VC4302ECB713 from Microchip Tech, in a SOT-23A-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 VOUT output Digital output (push-pot complementary on TC54VC) that goes low when VIN drops below VDET- and returns high when VIN rises above VDET- + VHYST.
2 VSS power_in Ground terminal providing the negative reference for the analog input voltage, typically circuit ground.
3 VIN power_in Analog input used for power supply monitoring or a voltage level that requires monitoring, operating range 0.7V to 10V (absolute maximum +12V).
