| PIN | TYPE(1) | DESCRIPTION | ||
|---|---|---|---|---|
| NAME | BQ2961 | BQ2962 | ||
| OUT | 8 | 7 | OA | Analog output drive for an overvoltage fault signal; CMOS output high or open-drain active low |
| PWPD | 9 | 9 | P | TI recommends connecting the exposed pad to VSS on PCB. |
| REG | 7 | 8 | OA | Regulated supply output. Requires an external ceramic capacitor for stability |
| REG_EN | — | — | IA | Regulated supply output enable. A "high" to enable REG output and "low" to disable REG output |
| V1 | 5 | 5 | IA | Sense input for positive voltage of the lowest cell from the bottom of the stack |
| V2 | 4 | 4 | IA | Sense input for positive voltage of the second cell from the bottom of the stack |
| V3 | 3 | 3 | IA | Sense input for positive voltage of the third cell from the bottom of the stack |
| V4 | 2 | 2 | IA | Sense input for positive voltage of the fourth cell from the bottom of the stack |
| VDD | 1 | 1 | P | Power supply input |
| VSS | 6 | 6 | P | Electrically connected to integrated circuit ground and negative terminal of the lowest cell in the stack |
(1) IA = Analog input, OA = Analog
Output, P = Power connection
