Are looking for an automotive qualified sensor offering robust, cost-effective solution to precisely monitor
- battery voltage
- current
- temperature?
Freescale Semiconductor has recently introduced the MM912J637 intelligent battery sensor (IBS), which accurately measures the voltage, current and temperature of lead-acid batteries and calculates the battery state, all while operating in harsh automotive conditions. The ability to accurately assess these battery parameters is becoming more important with increases in the number of hybrid vehicles on the road and overall electronic content in vehicles, as well as the introduction of start-stop systems.
The MM912J637 IBS offers a rugged and cost-effective solution for designers, enabling precision measurement of key battery parameters in automotive and industrial applications. The device integrates a S12 microcontroller and a SMARTMOS analog control integrated circuit in a single-package solution, enabling significant reduction of effective application board space. The MM912J637 IBS is designed to meet the highest automotive standards for electrostatic discharge, electromagnetic compatibility and zero defect quality levels. It is fully AEC-Q100 automotive qualified for operation from -40°C to +125°C, providing low power consumption in the target application. It comes in a small form factor, 7 x 7mm QFN package with wettable flanks technology, enabling optical inspection during assembly.
