Analog Front End (AFE) with Cell Balance and I2C communications with a microcontroller. Input: 4 7 cells series connected; Lithium Ion (Li-Ion), Li-Polymer,. Phosphate and Lead acid (PbA) battery cells. Output: Multiplexes and level shifts individual cell, battery pack, and chip internal temperature voltages DESCRIPTION. The bq24300 and bq24304 are highly integrated circuits designed to provide protection to Li-ion batteries from failures of the charging circuit. The IC continuously monitors the input voltage, the input current, and the battery voltage. The device operates like a linear regulator: for voltages up to the Input
