VDA1520CTA

AnaSem · Monitors & Reset Circuits · SOT-23

VDA1520CTA 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 Output pin that follows VIN when VIN is above the release voltage and is pulled to VSS when VIN falls below the detection voltage, with CMOS output for this part type.
2 VSS power_in Power ground reference for the device, with output voltage range stated as VSS -0.3V to VIN +0.3V.
3 VIN power_in Voltage input and supply pin with an operating voltage range of 0.7V to 6.0V and an absolute maximum input range of -0.3V to +7.0V.
