Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Chip supply pin; the recommended supply voltage is 3.2 V to 15 V, and the absolute maximum VCC is VSS-0.3 V to VSS+25 V. |
| 2 | B3 | input | Positive input of the third cell and negative input of the stack's top cell voltage sense; cell input range is 2.0 V to 4.5 V recommended, and B3 is limited to VSS-0.3 V to VCC+0.3 V. |
| 3 | B2 | input | Negative input of the third cell and positive input of the second cell; B2-B1 and B3-B2 voltages are limited to a minimum of -5 V. |
| 4 | B1 | input | Negative input of the second cell and positive input of the first cell; B1 is limited to VSS-0.3 V to VCC+0.3 V. |
| 5 | VSS | power_in | Negative terminal of the first cell and the chip ground reference for the device. |
| 6 | LM | input | Multi-function pin for discharge over-current voltage sensing (PDOC1 at 50/75/100/150 mV, PDOC2 at 2x PDOC1, short-circuit at 4x PDOC1), load-open detection (VLMTH 0.75 V) and charger detection; its absolute range is VSS-0.3 V to VCC+0.3 V and it sinks up to 70 µA at VLM = 5 V. |
| 7 | DDR | output | Discharge MOSFET gate driver output that swings between VSS (off) and VCC (on), sourcing up to 3 mA and sinking up to 5 mA, with a voltage range of VSS-0.3 V to VCC+0.3 V. |
| 8 | CDR | output | Charge MOSFET gate driver output that is pulled up with 6 µA when the charge MOSFET is on, with a voltage range of VCC-25 V to VCC+0.3 V. |
