Integrated HCS12 Based Relay Driver Microcontrollers (MCUs) with LIN

MM912_634

The MM912G634 (48 kB) and MM912H634 (64 kB) are integrated single package solutions that integrate an HCS12 MCU with a SMARTMOS® analog control IC. The Die to Die Interface (D2D) controlled analog die combines system base chip and application-specific functions, including a LIN transceiver.

Your customer benefits include:

  • Integrated MCU and analog features in the same package solution
  • A full LIN solution
  • Easy control of high-current motors using relays and current sense features
  • Reduced space, resulting in enhanced reliability
  • Full protection for output stages
  • Economical multifunction solution with few components
  • Low-power mode flexibility
  • Reverse-battery-protected voltage sense
