[原创] ST VNH5019A汽车马达驱动解决方案

ST公司的VNH5019A-E是全桥马达驱动器,集成了双路高边驱动器和两个低边开关,三个芯片封装在MultiPowerSO-30封装中,引线框是电绝缘的.汽车级产品,输出电流3A,3V CMOS兼容输入,PWM频率高达20kHz,用于各种汽车应用.本文介绍了VNH5019A主要特性,框图和 种应用电路,以及马达驱动评估板STEVAL-VNH5019A主要特性,电路图和材料清单.

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.
