【应用】拓尔微电机驱动芯片TMI8837助力智能门锁设计，低导通内阻仅650mΩ

时间： 2022-10-01 来源：世强

技术问答

在智能门锁的设计中，一般会用通过MCU对电机驱动芯片进行的正转、反转、刹车等功能的控制。本文推荐拓尔微TMI8837，如下图1为产品框图：

图1

拓尔微TMI8837是一颗H桥低压直流电机驱动，输入电压1.8V~12V，控制电源电压1.8V~7V，最大驱动电流可达1.5A。

TMI8837优势特点如下：

1、低导通内阻650mΩ（HS+LS），降低导通损耗；

2、EN脚低电平实现低功耗模式，VM睡眠模式电流45nA，VCC睡眠模式电流17nA；

3、拥有过流、短路、过温、欠压锁定等完备的保护功能；

4、DFN2x2-8封装，并且封装底部裸露焊盘可增强散热能力，封装见图2；

5、工作温度可达-40~125℃（Tj）。

图2

综上所述，拓尔微电机驱动芯片TMI8837非常适合应用于智能门锁设计。
