芯伯乐直流小电机驱动芯片L9110S介绍及设计
一、概述
XBLW L9110S是为控制和驱动电机设计的两通道推挽式功率放大专用集成电路,将分立电路集成在单片 IC 中,使外 围器件简单,整机成本降低的同时可靠性大大提高。芯片有两个 TTL/CMOS 兼容电平的输入,具有良好的抗干扰性;两个输出 端能直接驱动电机的正反向运动,它具有较大的电流驱动能力, 在散热条件良好 的情况下可输出高达800mA 的持续电流,峰值电流能力可达 1.5A;同时它具有较低的输出饱和压降。内置的钳位二极管能释放感性负载的反向冲击电流,使它在驱动继电器、直流电机、步进电机或开关功率管的使用上安全可靠。L9110被广泛应用于玩具电机驱动、脉冲电磁阀门驱动和其它直流电机驱动。
二、特点
●源电压范围:2.5V 至 12V
●大持续输出电流 800mA
●大峰值输出电流达到 1.5A SOP8封装
三、基本参数
●极限参数:1500mA / 2.5V-12V
●低静态工作电流: 0.1 uA
●宽电源电压范围:2.5V-12V
●每通道具有800mA 连续电流输出能力,精确快速的正反转控制
●超低的饱和电压降
●TTL/CMOS 输出电平兼容,可直接连CPU
●输出内置钳位二极管,适用于感性负载
●精确的脉宽控制和后级驱动集成于单片IC 之中
●具备管脚高压保护功能
●工作温度:-20 ℃-85 ℃
四、管脚定义及应用设计
使用单片机STM32F103控制XBLW L9110S驱动直流电机的设计
IB接的是PB8,IA接的是PB9 根据第二个图片里面的真值表我们可以得到如下信息:
PB8配置位复用推挽输出,PB9配置为通用推挽 然后我给PB8配置PWM波,PB9给拉低,那么电机是不是就是正转 反转同理 停止两个端口同时拉低或者拉高就行了。
接下里我们来配置一下PWM波,我们配置电机反转 PB9配置位复用推挽输出,PB8配置为通用推挽 然后我给PB9配置PWM波,PB8给拉低,那么电机是不是就是正转 ,看一下上图的定时器为TIM4,第4个管道。
驱动代码如下(通用)
这样我们是不是只需要改变配置里面的比较值(TIM4->CCR4)就可以实现电机的速度控制了 我们在主函数里这样简单测试一下,每延时3s我让比较值增加200:
TIM4->CCR4=200;
systick_ms(3000); TIM4->CCR4=400;
systick_ms(3000); TIM4->CCR4=600;
systick_ms(3000);
systick_ms(3000); TIM4->CCR4=800;
systick_ms(3000); TIM4->CCR4=1000;
systick_ms(3000);
五、当下主流的智能门锁设计方案
此方案用到的电机驱动芯片XBLW L9110S
以上是硬件设计方案及驱动代码,芯片可提供样品测试及技术支持。
我司国产电机类驱动芯片具有自主知识产权,能够满足国内市场的需求,提供稳定可靠的性能。这在一定程度上减少了对国外芯片的依赖,提高了国内集成电路产业的竞争力。

【成功案例】采用单通道H桥驱动器芯片HR9110的小型直流电机驱动系统设计
最近笔者设计了一个小型直流电机驱动系统。这个小型直流电机驱动系统采用了杭州中科微的一款应用于直流电机方案的单通道H桥驱动器芯片HR9110。选择这个型号主要是因为这个型号了解到在在小电机驱动比较有优势:内置PMOS、NMOS的单通道H桥驱动器,低导通电阻保证芯片具有极低的功率损耗,使得HR9110具有更长的工作时间。具有四种驱动功能:正传、反转、停转和刹车功能。可满足我设计的小电机系统工作要求。
