Figure 5-1 DDF Package8-Pin SOT-23Top ViewTable 5-1 Pin Functions
| PIN | I/O(1) | DESCRIPTION | |
|---|---|---|---|
| NO. | NAME | ||
| 1 | EN | I | Enable pin. Can be connected to ANODE for always ON operation. |
| 2 | GND | G | Ground pin |
| 3 | N.C | No connection. Keep this pin floating. | |
| 4 | VCAP | O | Charge pump output. Connect to external charge pump capacitor. |
| 5 | ANODE | I | Anode of the diode and input power. Connect to the source of the external N-channel MOSFET. |
| 6 | GATE | O | Gate drive output. Connect to gate of the external N-channel MOSFET. |
| 7 | N.C | No connection. Keep this pin floating. | |
| 8 | CATHODE | I | Cathode of the diode. Connect to the drain of the external N-channel MOSFET. |
(1) I = Input, O = Output, G = GND
