l293d集成电路说明[整理版]

l293d集成电路说明[整理版]

L293D采用16引脚DIP封装,其内部集成了双极型H-桥电路,所有的开量都做成n型。

这种双极型脉冲调宽方式具有很多优点,如电流连续;电机可四角限运行;电机停止时有微振电流,起到“动力润滑”作用,消除正反向时的静摩擦死区:低速平稳性好等。

L293D通过内部逻辑生成使能信号。

H-桥电路的输入量可以用来设置马达转动方向,使能信号可以用于脉宽调整(PWM)。

另外,L293D 将2个H-桥电路集成到1片芯片上,这就意味着用1片芯片可以同时控制2个电机。

每1个电机需要3个控制信号EN12、IN1、IN2,其中EN12是使能信号,IN1、IN2为电机转动方向控制信号,IN1、IN2分别为1,0时,电机正转,反之,电机反转。

选用一路PWM连接EN12引脚,通过调整PWM的占空比可以调整电机的转速。

选择一路I/O口,经反向器74HC14分别接IN1和IN2引脚,控制电机的正反转L293D集成电路说明L293DPUSH-PULL FOUR CHANNEL DRIVER WITH DIODES推拉4通道驱动带二极管600mA.

半导体集成电路 RD19230 型轴角-数字转换电路是一种小型、通用、低功耗的单片集成跟踪型 转换芯片,提供了可编程的分辨率、带宽以及速度电压输出等。分辨率可设置为 10、12、14 和 16 位,精度高达 2.4 角分。
内部合成参考不仅消除了由积分电路产生的误差,而且保证了参考与信号的相移小于 45 度时仍 能正常工作。速度电压(VEL)可替代转速计,输出范围为±4V(对地电压)。速度比例因子/跟踪 速率可以通过外接电阻来调整。转换芯片提供两套滤波参数选择,可以实现双带宽切换。
