Intelligent Battery Systems

Analog Devices provides complete system solutions for battery monitoring in 12V lead-acid automotive applications. These devices integrate all the required features to determine precisely and intelligently the battery state-of-charge and state-of-health. Minimizing external system components, these devices are powered directly from the 12V battery and feature ARM7™ integrated microcontrollers. This is used to pre-process the acquired battery variables and manage communications to the main electronic control unit (ECU) via a local interconnect network (LIN) interface that is also integrated on chip.
