Description
General part information
BQ77910 Series
The bq77910A is a battery protection and cell balancing device intended for Li-Ion and Li-Polymer battery packs.
The bq77910A monitors 4- to 10-series individual cell voltages and provides fast-acting outputs that may be used to drive N-channel MOSFETs to interrupt the power path. Activation delays and recovery methods for safety conditions are fully programmable in non-volatile memory.
Automatic cell balancing is provided using internal 50-mA cell circuits. A robust balancing algorithm ensures optimum performance by maintaining all cell voltages in balance. Balancing may be configured to operate at all times, only during charge, or can be disabled completely.
