摘　　要：在电机控制器中广泛应用死区电路来产生一对无重叠的PWM输出来正确启动和关闭功率晶体管,死区时间经常被插入到一个晶体管的关闭和另一个晶体管的开启之间。文章主要阐述自行设计的集成电机控制器中可编程死区的设计和实现方案。Dead-band circuit is widely used in motor control to get a pair of non-overlapping PWM outputs for the properly turn on and off the two transistor. A dead time (dead-band) is often inserted between the turning-off of one transistor and the turning-on of the other here. The designing of programming dead band in integrated motor controller of ourselves is introduced here, showing its high-efficiency and simpleness. 
