PRODMIX
The BQ2961 and BQ2962 devices are second-level overvoltage (OV) protectors with a regulated output. Each cell is monitored independently by comparing the actual cell voltage to an overvoltage threshold VOV. The overvoltage threshold is preprogrammed at the factory with a range between 3.85 V to 4.65 V.
The regulated output is enabled unless any of the cell voltages fall below the VUVREG threshold. This threshold is preprogrammed at the factory with a range between 2 V to 2.8 (3.5 V for future BQ2962 options).
| OVERVOLTAGE RANGE (V) | OVERVOLTAGE DELAY (s) | UNDERVOLTAGE RANGE (V) | REGULATOR (V) |
|---|---|---|---|
| 3.85 to 4.6 in 50-mV steps | 3, 4, 5.5, 6.5 | 2.0 to 2.8 (3.5 for future BQ2962 options) in 50-mV steps | 1.8, 2.5, 3.3 (BQ2961) 3.0, 3.15, 3.3 (BQ2962) |
