VNH7070AY Evaluation Board

VNH7070AY 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 ST proprietary VIPower^® M0 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 a PowerSSO-36 package equipped with three exposed islands for optimized dissipation performances.
This package is specifically designed for the harsh automotive environment and offers improved thermal performance thanks to exposed die pads. A Multisense_EN pin is available to enable the MultiSense diagnostic. The input signals INA and INB can directly interface the microcontroller to select the motor direction and the brake condition. Two selection pins (SEL0 and SEL1) are available to address the information available on the Multisense to the microcontroller. The Multisense pin allows to monitor the motor current by delivering a current proportional to the motor current value and also provides the diagnostic feedback. The PWM, up to 20 KHz, allows to control the speed of the motor in all possible conditions.
