2 to 5 Series Li-ion Battery Fuel Gauge IC

RAJ240071 and RAJ240075 (hereafter these are written as RAJ24007X) are Renesas Li-ion battery fuel gauge ICs (FGIC) which consists of an MCU device and an AFE device in a single package. Packed with a variety of battery management features and Renesas RL78 CPU core which has multiple low power modes and capable of achieving high performance in ultra-low power operation. RAJ24007X fuel gauge IC has control firmware stored in embedded flash memory to control attached embedded analog and digital circuits to execute battery voltage / current / temperature measurement, remaining capacity estimation, over current / voltage / temperature protection and other battery management operations.
