【应用】最大输出持续电流达4A的马达驱动芯片TMI8260SP用于智能门锁，宽输入电压范围5~18V

时间： 2023-03-27 来源：世强

技术问答

智能家居行业的持续火热，其中智能门锁产品凭借着指纹识别的高安全性受到了消费者的关注。近期拜访客户时，了解到客户智能门锁产品在找一个马达驱动芯片，因使用是电池供电，要求驱动芯片待机电流微安级，需有较大的驱动电流，世强推荐拓尔微电子的马达驱动芯片TMI8260SP，详细介绍一下其应用。

智能门锁的部分电路框图：

从框图中可以看出，指纹模块信号输入，通过SOC识别，输出INA、INB逻辑控制信号至TMI8260SP，TMI8260SP控制直流马达的前进，后退，停止，刹车的功能，达到智能门锁开锁，关锁的功能。

TMI8260SP的一些参数特性：

1、输入电压5V~18V，满足宽输入电压要求。

2、内置MOS，最大输出持续电流达4A，无需外加MOS，内阻较小约70mΩ。

3、极低的待机电流，典型值为1µA，损耗非常小。

4、具有紧急停止，过热保护，欠压保护，过流及短路功能，产品性能稳定。

5、HBM：±2000V，防静电能力较强，满足消费类产品应用环境。

6、工作温度范围-25℃~+85℃，满足消费类产品应用环境。

7、逻辑输入频率最高能支持50kHz，运行速度快。

8、通用SOP8封装，符合ROHS规范，引脚框架100%无铅。

9、典型参考应用电路图，外围元器件较少。

设计时注意事项

1、输入电容尽量靠近IC输入脚，及GND，将更好的消除输入纹波。输入电容与GND形成环路，必需尽量小。

2、负载峰值电流及持继工作电流，要小于芯片承受电流，需预有余量。

综上所示，TMI8260SP参数上有电压范围广，待机电流极小，电路外围元件少，应用简单，多种保护措施，性能稳定满足客户需求，在智能门锁产品中测试功能正常。在方案开发应用中，世强可以提供及时的技术服务，在货源上能给于稳定供货支持。
