RAA489220 4 to 10 Cell Battery Front End and Protector

RAA489220 4 to 10 Cell Battery Front End and Protector Datasheet The RAA489220 is a 10-cell Battery management Front End (BFE IC) with both autonomous protection functions and battery health monitoring for packs with MCU control (Figure 1). The RAA489220 monitors each cell for overvoltage, undervoltage, pack temperature, charge currents, and discharge currents. This device includes internal self test to confirm its own health, and system checks to confirm the system state. The I2C interface in.
