The bq77910 protects the battery pack by monitoring individual cell voltages and drives two N-channel power MOSFETs to interrupt current flow during fault conditions. Fault detection and recovery criteria for the device are fully programmable in non-volatile memory to suit all types of lithium battery systems.

Key features and benefits of the bq77910

  • Battery management and protection for 4- to 10-cell lithium batteries: Individual cell monitoring and balancing with internal FETs maximizes battery pack service life and performance.
  • Low power operation: Low quiescent current (50 uA typical, 2.5 uA in shutdown mode) minimizes battery discharge during storage or idle periods to optimize battery life.
  • Supports additional lithium battery chemistries: Programmable (EEPROM) fault detection thresholds and time delays make the bq77910 adaptable to all variations of lithium systems, including LiCoO2 and LiFePO4.
  • Standalone integrated solution does not require an external controller or processor.
