We offer a family of 3-phase brushless motor integrated drivers and gate drivers. The family of 3-phase brushless sensorless sinusoidal integrated drivers can be interfaced with any microcontroller (MCU) by using a simple PWM or can also be used stand-alone by the application. Our 3-phase brushless gate drivers can be used in combination with an MCU or Digital Signal Controller (DSC) that targets motor control applications.
Key Features of Integrated Motor Driver Family
- Sensorless 3-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
