Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | OVIN | input | Over-voltage detection input. Normally driven by an external resistor divider from the monitored rail. Rising threshold VOVTH+ = 1.211 V (typ), falling threshold VOVTH- = 1.12 V (typ). Input leakage ±100 nA max. |+| 2 | GND | power_in | Device ground reference. |+| 3 | OV | output | Over-voltage detection output, active-low, open-drain. Pulls low when OVIN rises above VOVTH+ (1.211 V typ); releases high when OVIN falls below VOVTH- (1.12 V typ). Requires external pull-up (e.g., 1 MΩ to VCC). Rated VOL = 0.3 V at ISINK up to 6 mA (VCC=5 V). |+| 4 | VCC | power_in | Positive supply input, 1.9 V to 6 V. Typical supply current 11 µA at 3.0 V. Absolute maximum 6.5 V. |+| 5 | UV | output | Under-voltage detection output, active-low, open-drain. Pulls low when UVIN falls below VUVTH- (1.12 V typ); releases high when UVIN rises above VUVTH+ (1.211 V typ). Requires external pull-up (e.g., 1 MΩ to VCC). Rated VOL = 0.3 V at ISINK up to 6 mA (VCC=5 V). |+| 6 | UVIN | input | Under-voltage detection input. Normally driven by an external resistor divider from the monitored rail.
