EV-VNH9045AQ

EV-VNH9030AQ, EV-VNH9045AQ and EV-VNH9090AQ provide you an easy way to connect ST VIPower M0-9 DC motor drivers into your existing prototype circuitry. This evaluation board comes preassembled with VNH90xxAQ. On board the minimum set of electrical components (as for device datasheet recommendation), enabling the user to directly connect the load, the power supply and the microcontroller without any additional effort in external component design and connection.

VNH90xxAQ 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 M09 technology which allows efficient integration of a true power MOSFET with intelligent signal/protection circuitry on the same die. The three dies are assembled in a QFN 6x6 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. 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 to the microcontroller the information available on the multisense pin and Phase_OUT pin. 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 Phase_OUT pin provides feedback of OUT status confirming the motor is driven properly.

The PWM, up to 25 kHz, allows to control the speed of the motor in all possible conditions.
