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. |
