ISL78714 Li-Ion Battery Management ICs

Renesas Electronics ISL78714 Lithium-Ion (Li-Ion) Battery Management ICs provide accurate cell voltage and temperature monitoring, cell balancing, and extensive system diagnostics to protect 14-cell Li-ion battery packs while maximizing driving time and range for hybrid and electric vehicles (HEV/MHEV/PHEV/BEV). The feature-rich Renesas ISL78714 monitors and balances up to 14 series-connected cells with ±2mV accuracy across automotive temperature ranges, letting system designers make informed decisions based on absolute voltage levels. The ISL78714 includes a precision 14-bit analog-to-digital converter and associated data acquisition circuitry. The device also offers up to six external temperature inputs (two available from GPIOs), including fault detection and diagnostics for all key internal functions. The ISL78714 comes in a 64-lead TQFP package and offers unmatched lifetime accuracy.
