S912ZVML31AWKH

S912ZVML31AWKH is a 16-bit S12 MagniV® S12ZVM mixed-signal microcontroller. It offers the smallest, most efficient, and scalable 3-phase motor control solution for Brushless Direct Current (BLDC) motor, Permanent Magnet Synchronous Motor (PMSM), or Switched Reluctance Motor (SRM) control applications for industrial and automotive. The S12ZVM MCU integrates a 12V to 5V voltage regulator, LIN physical layer or CAN physical layer, and a Gate Driver Unit (GDU) to control six power MOSFETs. Applications include 3-phase sensorless BLDC motor control for (fuel pump, water pump, oil pump, A/C compressor, HVAC blower, engine cooling fan, electric vehicle battery cooling fan), brush DC motor control requiring driving in 2 directions, along with PWM control for (reversible wiper, trunk opener).
