5 Pin Configuration and Functions
Figure 5-1 DBV Package6-Pin SOT-23Top ViewTable 5-1 Pin Functions
| PIN | I/O(1) | DESCRIPTION | |
|---|---|---|---|
| NO. | NAME | ||
| 1 | VCAP | O | Charge pump output. Connect to external charge pump capacitor |
| 2 | GND | G | Ground pin |
| 3 | EN | I | Enable pin. Can be connected to ANODE for always ON operation |
| 4 | CATHODE | I | Cathode of the diode. Connect to the drain of the external N-channel MOSFET |
| 5 | GATE | O | Gate drive output. Connect to gate of the external N-channel MOSFET |
| 6 | ANODE | I | Anode of the diode and input power. Connect to the source of the external N-channel MOSFET |
(1) I = Input, O = Output, G = GND
