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
