**AnaSem** · Monitors & Reset Circuits · SOT-23

VDA4310CTA 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 | CMOS output (C type) that goes low (VSS) when VIN falls below the detection voltage and follows VIN above the release voltage; output current rating is 50 mA max and the voltage range is VSS-0.3 to VIN+0.3 V. |
| 2 | VSS | power_in | Power ground pin. |
| 3 | VIN | power_in | Voltage input and monitored supply pin, with operating range 0.7 V to 6.0 V and absolute maximum of -0.3 to +7.0 V. |
