基于CS4124的脉宽直流驱动模块的设计与应用

Design and Application of Pulse Width DC Drive Module Based on CS4124

介绍了一种基于电机控制专用集成电路CS4124芯片的脉宽直流驱动模块的设计。驱动模块接收0~5V模拟信号后,通过驱动控制电路将其转换为PWM信号,再由场效应管驱动直流电机。该模块具有输出稳定、性能可靠,具备过压、过流、过热保护等特点。

This paper introduces a design of pulse width DC drive module based on the chip of motor control ASIC CS4124. Drive module receives 0 ~ 5 V analog signals,which are converted to PWM by means of the drive control circuit,and the DC motor is driven by the field effect tube. The driver has the characteristics of stable output,reliable performance,overvoltage protection,over heating protection,over-current protection and so on.
