EV-VNH7040AY: 28V @ 35A Automotive H-bridge Motor Driver

EV-VNH7040AY provides you an easy way to connect ST VIPower M0-7 H-Bridge drivers into your existing prototype circuitry. This evaluation board comes preassembled with VNH7040AY H-Bridge. The on-board minimum set of electrical components (as for device datasheet recommendation) enables the user to directly connect the load, the power supply and the microcontroller without any additional effort in external component design and connection.

VNH7040AY 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 provides the diagnostic feedback. The PWM, up to 20 KHz, allows to control the speed of the motor in all possible conditions.
