MM9Z1J638BM2EP NXP Battery Sensor IC | 48-QFN-EP(7x7) | I2C, SPI, LIN

Product Overview

The MM9Z1J638BM2EP is a highly integrated battery sensor IC from NXP Semiconductors, designed for precise monitoring of 12V lead-acid batteries in automotive and industrial applications. It combines a 16-bit microcontroller, a CAN/LIN transceiver, and multiple analog front-ends in a compact 48-QFN-EP (7x7 mm) package. The device measures battery voltage, current, and temperature, and calculates key parameters such as state-of-charge (SoC), state-of-health (SoH), and state-of-function (SoF). It supports I2C, SPI, and LIN communication interfaces, making it ideal for battery management systems (BMS) in vehicles, backup power systems, and energy storage.
