F2867 - VARIABLE SPEED SINGLE-PHASE FULL-WAVE PRE-DRIVER

General Description

The UTC F2867 is a single-phase bipolar variable speed driving motor pre-driver that works with external PWM signal.

A highly efficient, highly silent and low power consumption motor driver circuit can be achieved with a few external parts.

Key Features

  • S.
  • Pre-driver for single-phase full-wave drive Low-saturation drive using external PMOS-NMOS enables high-efficiency low power-consumption drive.
  • External PWM input enabling variable speed control Separately-excited upper direct PWM (f=30kHz) control method enabling highly silent speed control.
  • Current limiting circuit incorporated Chopper type current limit at start.
  • Reactive current cut circuit incorporated Reactive current before phase change is cut to enable silent and.
