描述 Description

The TLE94004EP is a protected four-fold half-bridge driver designed especially for automotive motion control applications such as Heating, Ventilation and Air Conditioning (HVAC) flap DC motor control. It is part of a larger family offering half-bridge drivers from three outputs to twelve outputs with direct interface or SPI. The half bridge drivers are designed to drive DC motor loads in sequential or parallel operation. Operation modes forward (cw), reverse (ccw), brake and high impedance are controlled via direct interface. It offers diagnosis features such as short circuit, power supply failure and overtemperature detection. In combination with its low quiescent current, this device is attractive among others for automotive applications. The small fine pitch exposed pad package, PG-TSDSO-14, provides good thermal performance and reduces PCB-board space and costs.

简介

TLE94004EP属于集成电路（IC）的全半桥驱动器。由制造生产的TLE94004EP全半桥驱动器器件属于电桥驱动器电源管理集成电路 (PMIC) 系列，包含两个或多个功率晶体管，以及在外部器件控制下将其用作开关所需的电路。这些晶体管通常在内部配置为成对串联连接（称为半桥），因而任意指定晶体管对之间的结点都可以连接至两个电源轨中的任一个。这类器件常用于将控制器件（如微控制器）提供的低电平信号转换为操作执行器（如步进电机或无刷电机）所需的较大功率信号。
