Description
General part information
BQ77PL900 Series
The bq77PL900 is a five to ten series cell lithium-ion battery pack protector. The integrated I2C communications interface allows the bq77PL900 also to be as an analog front end (AFE) for a Host controller. Two LDOs, one 5 V/25 mA and one 3.3 V/25 mA, are also included and may be used to power a host controller or support circuitry.
The bq77PL900 integrates a voltage translation system to extract battery parameters such as individual cell voltages and charge/discharge current. Variables such as voltage protection thresholds and detection delay times can be programmed by using the internal EEPROM.
The bq77PL900 can act as a stand-alone self-contained battery protection system (stand-alone mode). It can alternatively be combined with a host microcontroller to offer fuel gauge or other battery management capabilities to the host system (host-control mode).
