Microchip 3 Phase MOSFET Driver
3 Phase MOSFET Driver
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.
Main 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
