Battery Management

5-10SLi-ion protectionLi-polymer protectionBattery AFECell balancingSSOP-48I²C-compatible

BQ77PL900DL is a 48-pin battery protection AFE for 5 to 10 series Li-ion/Li-polymer cells, combining programmable protection, PMOS FET drive, cell balancing, and analog monitoring.

Best for

  • 5S to 10S Li-ion or Li-polymer battery packs
  • Standalone battery protection designs
  • Host-controlled packs needing analog cell and current outputs

Avoid if

  • A battery monitor requiring more than 10 series cells
  • A design requiring unrestricted standard I²C behavior
  • A design that cannot accommodate a 48-pin SSOP package

Check before use

  • Confirm CNF0, CNF1, and CNF2 cell-count configuration.
  • Verify OV, UV, OCD, and SCD EEPROM settings against cell and FET limits.
  • Ensure unused cell inputs are tied as specified in the datasheet.
  • Verify PMOS FET gate-drive and zero-volt/precharge topology.
