RAA489206 is a 16-cell Battery Front End (BFE) IC, an essential component of any Battery Management System (BMS) that periodically scans battery status and the operating environment to optimize battery life and prevent catastrophic failures. To manage the overall state of the battery pack, a differential multiplexer and 16bit ADC allow for the accurate monitoring of cell voltage, temperature and load current. The RAA489206 supports I2C, SPI and SPI w/CRC protocols allowing customers to connect an MCU in a proprietary battery management solution. Low current consumption with an average IDLE mode current of 200µA and a SHIP mode current of less than 18µA maximizes the storage and discharge life of a battery pack. Applications include light electric vehicles such as e-bikes, e-scooters, and e-motorcycles, cordless power and gardening tools, home appliances, 24V, 36V, 42V, and 48V portable battery packs, telecom and server farms, solar farms and energy storage systems.
