BQ294712DSGT, Battery Management Lithium-ion protection for accurate cell-by-cell voltage monitoring 8-WSON -40 to 110
Power\Power Management ICs\Battery Managementbq2947 Lithium-ion Protection ICs Texas Instruments bq2947 Lithium-ion Protection ICs are overvoltage monitors and protectors for Li-Ion battery pack systems. Each cell is monitored independently for an overvoltage condition. In the bq2947 device, an external delay timer is initiated upon detection of an overvoltage condition on any cell. Upon expiration of the delay timer, the output is triggered into its active state (either high or low, depending on the configuration). The external delay timer feature also includes the ability to detect an open or shorted delay capacitor on the CD pin, which will similarly trigger the output driver in an overvoltage condition. For quicker production-line testing, the bq2947 device provides a Customer Test Mode with reduced delay time.
