ST VHN5019A－E汽车H桥马达驱动解决方案

ST公司的VHN5019A-E是全集成的汽车H桥马达驱动器,包括两个高边驱动器和两个低边开关,无铅和RoHS兼容的ECOPACK®,和AEC兼容的汽车级产品,3V CMOS兼容输入,输出电流30A,DC-20kHz PWM工作,具有智能信号和保护特性.本文介绍了VHN5019A-E主要特性,框图, 典型应用电路和多个马达配置图,以及评估板STEVAL-VNH5019A主要特性,主板和子板电路图与PCB设计图.

The VHN5019A-E is a full bridge motor driver intended for a wide range of automotive applications. The device incorporates a dual monolithic high-side drivers and two low-side switches. The high-side driver switch is designed using STMicroelectronics’ well known and proven proprietary VIPower® M0 technology that allows to efficiently integrate on the same die a true Power MOSFET with an intelligent signal/protection circuit.

The three dice are assembled in MultiPowerSO-30 package on electrically isolated lead-frames. This package, specifically designed for the harsh automotive environment offers improved thermal performance thanks to exposed die pads. The input signals INA and INB can directly interface to the microcontroller to select the motor direction and the brake condition.
