Reference Designs

This reference design consists of a bq77908A circuit module and a resistor cell simulator module: which can be used for simple evaluation of the IC functions used in consumer electronics applications. The reference design includes one bq77908A integrated circuit (IC): sense resistor: power FETs and all other onboard components necessary to protect the cells from overcharge: overdischarge: short circuit: and overcurrent discharge in a 8-series cell Li-Ion or Li-Polymer battery pack. The circuit module connects directly across the cells in a battery. With a compatible interface board and Windows®-based PC software: the user can view the bq77908A registers and program the IC configuration and protection limits.
