Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VC1 | power_in | Chip power supply pin, connected to the positive terminal of battery 1, with absolute maximum VC1 to VSS of -0.3 V to +30 V. |
| 2 | VC2 | input | Connects the negative terminal of battery 1 and the positive terminal of battery 2 for cell voltage sensing, with each cell-voltage absolute maximum of -0.3 V to 6.5 V. |
| 3 | VC3 | input | Connects the negative terminal of battery 2 and the positive terminal of battery 3 for cell voltage sensing, with each cell-voltage absolute maximum of -0.3 V to 6.5 V. |
| 4 | VSS | power_in | Chip ground and connection to the negative terminal of battery 3, the reference for all voltage ratings on the device. |
| 5 | RTS | input | Connects to the NTC thermistor for temperature detection, with input voltage absolute range VSS-0.3 V to VSS+6.5 V. |
| 6 | RTV | passive | Connects through a resistor to the RTS terminal to set the high-temperature protection point (RT = 3 x RNTC), with input voltage absolute range VSS-0.3 V to VSS+6.5 V. |
| 7 | VIN | power_in | Discharge overcurrent and short-circuit detection input, with absolute range VSS-0.3 V to VSS+6.5 V and thresholds of 0.100 V (VEC1), 0.200 V (VEC2), 0.400 V (VSHORT) and -0.100 V (charge overcurrent VCHA). |
