24V Single Phase Brushless DC Motor Driver

Download Datasheet

  • Description

    The NJW4321 is a single phase motor driver IC for 24V FAN Motor. It features a PWM Soft-Switching that provides low vibration and high efficiency motor driving. Built-in protection circuits: Lock Protection, Over Current Detection and Thermal Shutdown contribute to enhance safety. The speed control corresponds to two modes of Direct PWM Input and DC Voltage Input. In addition, the speed control function at the DC Voltage Input Mode is enhanced, and the Duty Slope setting and the Minimum Speed setting can be performed.
