VNH7070BAS数据手册集成电路（IC）的电机驱动器控制器规格书PDF

描述 Description

The device is a full bridge motor driver intended for a wide range of automotive applications. The device incorporates a dual monolithic high-side driver and two low-side switches.

Both switches are designed using STMicroelectronics’ well known and proven proprietary VIPower®M0-7 technology that allows to efficiently integrate on the same die a true Power MOSFET with an intelligent signal/protection circuitry. The three dies are assembled in SO-16N package on electrically isolated lead-frames.

Moreover, its fully symmetrical mechanical design allows superior manufacturability at board level. The input signals INAand INBcan directly interface the microcontroller to select the motor direction and the brake condition. A SEL0 pin is available to address the information available on the CS to the microcontroller. The CS pin allows to monitor the motor current by delivering a current proportional to the motor current value. The PWM, up to 20 kHz, allows to control the speed of the motor in all possible conditions. In all cases, a low level state on the PWM pin turns off both the LSAand LSBswitches.
