3 to 10 Series Li-ion Battery Fuel Gauge IC

RAJ240310 is Renesas Li-ion battery fuel gauge IC (FGIC) which consists of a MCU device and an AFE device in a single package. Packed with a variety of battery management features and a Renesas RL78 CPU core which has multiple low power modes, and achieves a high performance under ultra-low power operation. RAJ240310 has embedded flash memory on an MCU (same as other RL78 family) and use it to store program instructions (code) as well as data on to perform battery voltage / current / temperature measurement, remaining capacity estimation, over current / voltage / temperature protection and other battery management operations.
