VDD221MCTA

AnaSem · Voltage Reference · SOT-23

VDD221MCTA 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; it is pulled to VSS when VIN falls below VDET and follows VIN after release, with CMOS or N-channel open-drain output depending on the ordered output type (the VDD221MCTA is CMOS output), and absolute maximum output voltage range VSS-0.3 V to VIN+0.3 V and output current 50 mA.
2 VSS power_in Power ground reference pin for the device.
3 VIN power_in Voltage input pin that supplies the device and is the monitored voltage, with an operating voltage range of 0.7 V to 6.0 V and an absolute maximum rating of -0.3 V to +7.0 V.
