NXP Semiconductors Data sheet: Technical data Document Number: MM912_637D1 Rev. 6.0, 6/2021 Intelligent integrated precision battery sensor MM912_637 The MM912I637 (96 kB) and MM912J637 (128 kB) are fully integrated LIN Battery monitoring devices, based on NXP SMARTMOS and S12 MCU Technology. The device supports precise current measurement via an external shunt resistor, and precise battery voltage measurement via a series resistor directly at the battery plus pole. The integrated temperature sensor combined in the close proximity to the battery, allows battery temperature measurement. The integrated LIN 2.1 interface makes the sensor feedback available on the LIN Bus.
