产品简介
为了安全起见，锁定关闭功能将关闭IC的内部驱动器，避免转子锁定时过热，IC将在这些驱动器关闭后尝试重新启动转子扭矩。
热关机保护（TSD）确保IC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，并保证在正确和安全的操作下。

一.产品概述
CXMD3219AH is a single-phase full wave motor driver with embedded Hall-effect sensor IC. It integrates a H-bridge MOS driver, a high sensitivity hall-effect sensor, an event timer for rotor locked in SIP-4L package, which make the motors’ PCBs(printed circuit boards) design easy and fabricate the high efficiency DC motors or FANs as simply as possible.
For safety, Lock-shutdown function would turn the IC’s internal drivers off avoiding over-heat when the rotor is locked, and IC will try to re-start the rotor’s torque after the time of these drivers’ shutdown.
Thermal-shutdown protection (TSD) ensures the internal drivers of IC are operating under a safe operating temperature range.
All the protection mechanisms mentioned above combine to provide a complete protecting scenario in the motor system and avoid any possible damages and guarantee under a correct and safe operation.
