NCV303LSN45T1G from onsemi, in a TSOP-5. 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 | Reset Output | output | Active-low reset output of the NCP303 open-drain N-channel type, which can be pulled up to VP through RP; the maximum output voltage is 12 V and the maximum output current is 70 mA. |
| 2 | Input | input | Monitored supply input (Vin) for the undervoltage detector, rated to a maximum of 12 V, with a specified operating voltage range of 0.8 V to 10 V. |
| 3 | GND | power_in | Ground reference pin for the device. |
| 4 | N.C. | unconnected | No internal connection; the datasheet does not specify a function for this pin. |
| 5 | CD | passive | Delay capacitor pin that sets the reset time delay tD via an external capacitor, with an internal pull-up of about 1.0 MΩ and a voltage range of −0.3 V to Vin + 0.3 V. |
