| IC1 | RAA489204 | 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 external |
