bq77PL900 Overview
The bq77PL900 is a five to ten series cell lithium-ion battery pack protector. The integrated I2C munications 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.
