Motor Drivers

The family of 3-Phase brushless motor gate drivers from Microchip can provide a simple interface between a microcontroller and a BLDC motor. They offer several protection features and can withstand high ambient temperatures, which make them ideally suited for use in harsh automotive environments, including underhood applications.

Main features of motor gate driver family:
  • Three half-bridge drivers configured to drive external NMOS MOSFETs
  • Shoot-through protection
  • Overcurrent and short circuit protection
  • Adjustable output buck regulator
  • Operational amplifiers for motor phase current monitoring and position detection
  • Overcurrent Comparator
  • Level Translators
  • UVLO; OVLO; thermal warning and shutdown
  • Load dump protection
  • High Temperature Range: -40 to +150°C ambient
