CXHA3126高灵敏度霍尔效应传感器12V至48V直流电机风扇系统锁定关机保护和自动重启功能边缘检测器和传播延迟定时器互补的双前置驱动器输出与嵌入式霍尔效应传感器集成电路

CXHA3126是一个互补的双前置驱动器输出与嵌入式霍尔效应传感器集成电路。它集成了用于NPN或NMOS驱动器的输出钳位图腾磁极驱动器、高灵敏度霍尔效应传感器、SIP-4L封装的转子锁定事件计时器，使该解决方案尽可能简单地在直流电机或风扇的高功率条件下运行。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

---

     CXHA3126 is a complementary dual pre-drivers output with embedded Hall-effect sensor IC. It integrates a output clamping totem-pole drivers for NPN or NMOS drivers, a high sensitivity hall-effect sensor, an event timer for rotor locked in SIP-4L package, which make this solution operation under a high power conditions of 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.
