KIT912J637EVME: Evaluation Kit - MM912J637,12V Lead-acid Battery Sensor ARCHIVED

Overview

Archived content is no longer updated and is made available for historical reference only.

This evaluation module supports the MM912J637, a fully integrated LIN Battery monitoring device based on the NXP^® S12 MCU technology.

Supports precise current measurement via an external shunt resistor, precise battery voltage measurement via a series resistor directly at the battery plus pole
The temperature sensor combined with the close proximity to the battery allows battery temperature measurement
The integrated LIN 2.1 interface makes sensor feedback available on the LIN Bus
