Product Summary
The BQ77PL900DL is a five to ten series cell lithiumion battery pack protector. The integrated I2C communications interface allows the BQ77PL900DL 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 applications of the BQ77PL900DL include Cordless Power Tools, Power Assisted Bicycle/Scooter, Uninterruptible Power Supply (UPS) Systems, Medical Equipment and Portable Test Equipment.
