General Description

This motor driver IC adopts PrestoMOS™ as the output transistor, and put in a small full molding package with the 120° square wave commutation controller chip and the high voltage gate driver chip.

The protection circuits for overcurrent, overheating, under voltage lock out and the high voltage bootstrap diode with current regulation are built-in.

It provides optimum motor drive system and downsizing the built-in PCB of the motor.

Key Features

  • 600V PrestoMOS™ built-in.
  • Output current 2.5A.
  • Bootstrap operation by floating high side driver (including diode).
  • 120° square wave commutation logic.
  • PWM control.
  • Rotational direction switch.
  • FG signal output with pulse number switch (4 or 12).
  • VREG output (5V/30mA).
  • Protection circuits provided: CL, OCP, TSD, UVLO, MLP and the external fault input.
  • Fault output (open drain).
