PRODUCTION DATA
PIN | I/O(1) | DESCRIPTION | |
---|---|---|---|
NO. | NAME | ||
1 | GATE | O | Gate drive output. Connect to gate of the external N-channel MOSFET. |
2 | ANODE | I | Anode of the ideal diode and input power. Connect to the source of the external N-channel MOSFET. |
3 | VCAP | O | Charge pump output. Connect to external charge pump capacitor. |
4 | SW | O | Voltage sensing disconnect switch terminal. ANODE and SW are internally connected through a switch when EN is high. A resistor ladder from this pin to GND can be used to monitor battery voltage. When EN is pulled low, the switch is OFF disconnecting the resistor ladder from the battery line thereby cutting off the leakage current. |
5 | GND | G | Ground pin |
6 | EN | I | Enable pin. Can be connected to ANODE for always ON operation. |
7 | N.C | — | No connect. Keep this pin floating. |
8 | CATHODE | I | Cathode of the ideal diode. Connect to the drain of the external N-channel MOSFET. |
