Freescale announces availability of intelligent battery sensor with MCU and CAN

Freescale Semiconductor has announced availability of AEC-Q100 qualified intelligent battery sensor to combine three measurement channels, a 16/32-bit MCU, and a CAN protocol module in a single package.

Designed to support both conventional and emerging battery chemistries for automotive and industrial applications, the MM9Z1J638 battery sensor measures key battery parameters for monitoring state of health (SOH), state of charge (SOC) and state of function (SOF) for early failure prediction. A flexible four-cell front-end architecture supports conventional 12V lead acid batteries as well as emerging battery applications, such as 14V stacked cell Li-Ion, high-voltage junction boxes, and 24V truck batteries.

“Our introduction of the industry’s first single-package, automotive-qualified intelligent battery sensor with MCU and CAN components will help automakers cope with increasing algorithm complexity and data communication demands as cars become more connected and intelligent. Also featuring integrated functional safety support, the new MM9Z1J638 battery sensor helps to support vehicle reliability even as automotive electrical system complexities increase,” said James Bates, Senior Vice-President & General Manager for Freescale’s Analog & Sensors Group.

Integrating a 16/32 bit S12Z microcontroller with 128K Flash, 8K RAM and 4K EEPROM together with a CAN protocol module, LIN interface and a three-channel analog measurement front end, the MM9Z1J638 battery sensor combines analog, processor and communication functions in a single package to help lower total bill of materials and accommodate advanced battery monitoring algorithms.
