摘要
设计了基于MC33886芯片的新型智能车电机驱动电路,详细分析了芯片的特点以及电路功能.在驱动电路的输出端加入了短路自动断电保护电路.对驱动电路进行了20KHz、40%占空比的PWM驱动实验,证明该电路能够很好的实现电机驱动.
A new motor driver circuit based on MC33886 for smart car is designed. This paper explains the characteristics of the chip and the theories of circuit particularly. An automatic protective circuit at the output port is added, which can cut off when the circuit is shorted. The circuit is tested with PWM wave with 20 KHz frequen- cy and the duty cycle is 40%. The results prove that the circuit can drive the motor well.
