## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VG | power_out | Internal voltage modulator output that powers the internal drive circuitry, requiring a 100nF capacitor between VG and VCC; VG-to-VCC voltage is limited to -8V to VCC+0.3V. |
| 2 | GND | power_in | Ground, serving as the negative input of the input supply and the battery negative terminal; all voltages are referenced to GND with a maximum rating of 33V for VCC, VG, DRV, CHRG and DONE. |
| 3 | CHRG | output | Open-drain charge status output that is pulled low by an internal transistor during charging and is high-impedance otherwise, rated up to 33V. |
| 4 | DONE | output | Open-drain charge-complete status output that is pulled low by an internal transistor in the charge-complete state and is high-impedance otherwise, rated up to 33V. |
| 5 | COM | passive | Loop compensation input, requiring a 120Ω resistor in series with a 220nF capacitor from COM to GND; COM-to-GND voltage is limited to -0.3V to 6.5V. |
| 6 | FB | input | Battery voltage sense input that senses the battery positive terminal; a resistor between FB and BAT raises the constant-voltage charge level, with FB-to-GND limited to -0.3V to 25V. |
| 7 | BAT | bidirectional | Battery positive connection and negative input of the charge-current sense, measuring the voltage across RCS together with CSP; BAT-to-GND voltage is limited to -0.3V to 25V. |
| 8 | CSP | input | Positive input of the charge-current sense, measuring the voltage across the sense resistor RCS together with BAT; CSP-to-GND voltage is limited to -0.3V to 25V. |
| 9 | VCC | power_in | External supply positive input that also powers the internal circuits, requiring a filter capacitor to GND; operating input range is 6.6V to 30V. |
| 10 | DRV | output | Gate drive output that drives the external P-channel MOSFET gate, clamped so that its low level is at most 8V below VCC. |
