Automotive Monitoring Function Extension

Renesas offers monitoring functions using a tiny CMIC^*1 in a variety of motor control applications. CMIC GreenPAK™ is a cost-effective NVM^*2 programmable device that allows automotive designers to integrate many system functions into a single AEC-Q100 qualified IC, resulting in minimizing component count and board space.

System Benefits:

• Provides an overcurrent detection system using a shunt resistor for 12V motor systems and a current sensor for xEV motor systems.
• Provides motor rotation position detection through a zero-cross comparator in a square-wave motor controller system.
• Enables retrofitting the CMIC to existing designs.
• The GreenPAK designer software/development kit enables quick modification to changing design requirements and increases productivity at the design and prototype verification stages.
