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. |
