Battery Sensor with LIN for 12 V Lead-Acid Batteries
The NXP® MM912_637 battery sensors are integrated battery monitoring devices that allow simultaneous measurement of current and voltage for precise determination of SOC (State of Charge), SOH (State of Health), and other parameters.
- The integrated temperature sensor combined with the close proximity to the battery allows battery temperature measurement
- Multiple application-specific hardware blocks reduce MCU overhead and related power consumption
- Configurable low-power modes with automated battery state observation and sophisticated wake-up capability further reduce current consumption
- The integrated LIN 2.1 interface allows communication and control of battery monitoring functions
