Freescale Intelligent Battery Sensor Combines MCU and CAN with Flexible Three-Channel Analog Front End

Freescale Semiconductor (NYSE:FSL) today announced the availability of the industry’s first general market 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.

Battery failure is one of the leading causes of vehicle breakdowns due to electrical system errors. Rising levels of electrical load in vehicles are placing increased strain on batteries as new, mission-critical requirements such as engine start-stop functionality become increasingly common. According to analyst firm Strategy Analytics, more than 52 million vehicles worldwide will support start-stop functionality by 2020. Start-stop requirements, together with others such as regenerative braking and intelligent alternator control, are driving demand for more precise sensing of the battery’s state to provide early failure warnings.

“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,” said James Bates, senior vice president and general manager for Freescale’s Analog & Sensors Group. “Also featuring integrated functional safety support, the new MM9Z1J638 battery sensor helps to support vehicle reliability even as automotive electrical system complexities increase.”

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. The analog front end includes a two-channel, 16-bit sigma delta (ΣΔ) analog-to-digital converter (ADC) for simultaneous measurement of battery voltage and current, as well as a third 16-bit ΣΔ ADC for temperature monitoring using the integrated sensor and redundant measurement plausibility checks to support functional safety. The new Freescale product’s input battery voltage measurement capability supports a wide range up to 52V directly to the device as well as much higher voltage battery configurations when used with external voltage dividers. Its low operating duty cycle enables operation in low-power mode for a majority of the time to help lower average system power consumption. The MM9Z1J638 is fully AEC-Q100 automotive qualified and designed to meet stringent automotive standards for ESD, EMC and zero defect quality levels.

Development Support

Reference designs with integrated hardware and software support for the MM9Z1J638 battery sensor enable quick and easy development of new applications, including energy storage systems, uninterruptible power supplies, hospital equipment and alarm systems. Low-level drivers and BMS utility libraries are available to support custom battery modeling and shorten development cycles. The KIT9Z1J638EVM evaluation board is priced at $188.80(USD) and demonstrates key features of the MM9Z1_638. Reference design RD9Z1-638-4Li is priced at $220.80(USD) and demonstrates product capabilities for 4-cell Li-Ion battery applications.

Enterprises are universally struggling to understand where the new tools and methodologies of DevOps fit into their organizations, and are universally making the same mistakes. These mistakes are not unavoidable, and in fact, avoiding them gifts an organization with sustained competitive advantage, just like it did for Japanese Manufacturing Post WWII.
When building large, cloud-based applications that operate at a high scale, it's important to maintain a high availability and resilience to failures. In order to do that, you must be tolerant of failures, even in light of failures in other areas of your application. "Fly two mistakes high" is an old adage in the radio control airplane hobby. It means, fly high enough so that if you make a mistake, you can continue flying with room to still make mistakes. In his session at 18th Cloud Expo, Le...
