VDD331MCTA

AnaSem · Monitors & Reset Circuits · SOT-23

VDD331MCTA from AnaSem, in a SOT-23. 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 Detector output (CMOS or N-channel open drain depending on the C/N code), which goes low when VIN falls below VDET and is released after the delay time once VIN rises above VREL; maximum output current is 50 mA.
2 VSS power_in Power ground pin of the detector.
3 VIN power_in Voltage input pin, operating range 0.7V to 6.0V with an absolute maximum of -0.3V to +7.0V.
