CXMD3205是一款单相全波电机驱动器，内置霍尔效应传感器。它集成了一个H桥MOS驱动器、一个高灵敏度霍尔效应传感器、一个用于锁定转子检测的事件计时器，以及带有转速表或报警信号输出逻辑的变速控制功能到超小型TS826组件中，这使得电机的PCB（印刷电路板）设计更容易，小型直流电机或风扇的制造也尽可能简单。外部系统可以从CXMD3205的FG信号中读取电机的转速。为安全起见，锁定关闭功能关闭IC的内部驱动器，以避免转子锁定时过热，在停机间隔后，IC将尝试重新启动电机。热关机保护（TSD）确保IC的内部驱动器在安全工作温度范围内工作。上述所有保护机制结合起来，在电机系统中提供完整的保护方案，避免任何可能的损坏和保证操作正确、安全。

一.产品概述
CXMD3205 is a single-phase full-wave motor driver with embedded Hall-effect sensor. It integrates a H-bridge MOS driver, a high sensitivity Hall-effect sensor, an event timer for locked rotor detection, and the variable speed controlfunction with the tachometer or alarm signal output logic into the ultra-small TS826 package, which make themotors’ PCB (printed circuit board) design easier and the fabrication of small-size DC motors or FANs as simple aspossible.The external system could read the motor’s speed of rotation from FG signal of CXMD3205.For safety, Lock-shutdown function turns the IC’s internal driver off to avoid over-heating when the rotor is locked,and the IC will try to re-start the motor after the shutdown interval.Thermal-shutdown protection (TSD) ensures the internal driver of IC is operating under the safe operatingtemperature range.All the protection mechanisms mentioned above combine to provide a complete protecting scenario in the motorsystem and avoid any possible damages and guarantee under a correct and safe operation.
