Description
Renesas’ daisy chainable 14-cell battery front-end is ideal for high voltage, stacked battery systems. The RAA489204 is a 14-cell battery front-end (BFE) IC, an essential component of any battery management system (BMS), which periodically scans battery status and the operating environment to optimize battery life and prevent catastrophic failures. The part provides accurate monitoring, cell balancing, and extensive system diagnostics functions. Cell balancing can be conducted either internally or externally, with 10V gate pins for external balancing.
The RAA489204 Li-ion battery manager IC supervises up to 14 series connected cells. The part provides accurate monitoring, cell balancing, and extensive system diagnostics functions. Three cell balancing modes are provided: Manual Balancing mode, Timed Balancing mode, and Auto Balance mode. The Auto Balance mode terminates balancing functions when a charge transfer value has been met. The RAA489204 communicates to a host microcontroller via an SPI interface and to other RAA489204 devices using a robust, proprietary, two-wire daisy chain system. The RAA489204 is offered in a 64 Ld TQFP package and is specified for an operational temperature range of -40 °C to +85 °C.
