Microchip offers a family of three-phase brushless motor drivers and gate drivers. The family of three-phase brushless sensorless sinusoidal motor drivers can be interfaced with any microcontrollers by using a simple PWM, or can also be used stand-alone by the application. The family of three-phase brushless gate drivers is ideal to be designed with microcontrollers or digital signal controllers.

Key Features of Motor Driver Family

  • Sensorless three-phase brushless motor drivers (no hall-effect sensor required)

  • 180° sinusoidal drive, for high efficiency and low acoustic noise

  • Speed control through power supply modulation (PSM) and/or pulse-width modulation (PWM)

  • Direction control pin (MTD6502B and MTD6505)

  • Resistor programmable BEMF coefficient (MTD6505)

  • Motor speed output (FG)

  • Lockup protection and automatic recovery

  • Over-current Limit, short circuit, and over-temperature protection

Key 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 (MCP8024, MCP8025, MCP8026)

  • Operational amplifiers for motor phase current monitoring and position detection (MCP8024, MCP8025, MCP8026)

  • Overcurrent Comparator  (MCP8024, MCP8025, MCP8026)

  • Level Translators

  • UVLO; OVLO; thermal warning and shutdown

  • Load dump protection, Jumpstart capability

  • Extended Temperature Range: -40 to +150°C

  • High junction temperature 200°C (ATA6844)
