VNH7100AS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 automotiveapplications. The device incorporates a dual monolithic high-side driver and two low-sideswitches.
Both switches are designed using STMicroelectronics’ well known and proven proprietaryVIPower® M0 technology that allows to efficiently integrate on the same die atrue Power MOSFET with an intelligent signal/protection circuitry. The three dies areassembled in SO-16N package on electrically isolated leadframes.
Moreover, its fully symmetrical mechanical design allows superior manufacturability at boardlevel. The input signals INA and INB can directly interface themicrocontroller to select the motor direction and the brake condition. A SEL0 pin is availableto address the information available on the MultiSense to the microcontroller. The MultiSensepin allows to monitor the motor current by delivering a current proportional to the motorcurrent 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 LSA andLSB switches.
