Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OD | output | MOSFET gate connection pin for discharge control; the OD output voltage is limited to VSS-0.3 V to VDD+0.3 V. |
| 2 | OC | output | MOSFET gate connection pin for charge control; the OC output voltage is limited to VDD-33 V to VDD+0.3 V. |
| 3 | CS | input | Input pin for current sense and charger detection; the CS input voltage is limited to VDD-33 V to VDD+0.3 V. |
| 4 | VC | input | Input pin for the center voltage between the two cells; the datasheet gives no separate voltage limit for this pin. |
| 5 | VDD | power_in | Power supply pin; the operating voltage between VDD and VSS is 1.5 V to 10 V, with an absolute maximum input of VSS-0.3 V to VSS+10 V. |
| 6 | VSS | power_in | Ground pin and 0 V reference for all voltage ratings of the IC. |
