BQ77908AEVM-001

TEXAS INSTRUMENTS BQ77908AEVM-001 Evaluation Module, Power Management, Battery Monitor, BQ77908A

The bq77908AEVM-001 evaluation module is a complete evaluation system for the bq77908A, a 4-series to 8-series cell Li ion battery protection integrated circuit. The evaluation module consists of a bq77908A circuit module and a resistor cell simulator module, which can be used for simple evaluation of the bq77908A functions. The circuit module includes bq77908A integrated circuit IC, sense resistor, power FETs and all other onboard components necessary to protect the cells from overcharge, over discharge, short circuit, and over current 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.
