EVAL-VNH5019-P1: 12A, 5.5 ~ 24V, Motor Driver

This carrier board for ST's VNH5019 motor driver IC operates from 5.5 to 24 V and can deliver a continuous 12 A (30 A peak). It works with 2.5 to 5 V logic levels, supports ultrasonic (up to 20 kHz) PWM, and features current sense feedback (an analog voltage proportional to the motor current). Along with built-in protection against reverse-voltage, over-voltage, under-voltage, over-temperature, and over-current, these features make this product a great general-purpose motor driver.

This module is a compact breakout board for ST's high-power VNH5019 motor driver IC, a fully integrated H-bridge that can be used for bidirectional speed control of a single brushed DC motor. The board incorporates most of the components of the typical application diagram on page 14 of the VNH5019 datasheet, including pull-up and current-limiting resistors and a FET for reverse battery protection. It ships fully populated with its SMD components, including the VNH5019

Features

• Operating voltage: 5.5 - 24V

• Output current: 12 A continuous (30 maximum)

• 3V-compatible inputs

• PWM operation up to 20 kHz, which is ultrasonic and allows for quieter motor operation

• Current sense output proportional to motor current (approx. 140 mV/A; only active while H-bridge is driving)

• Motor indicator LEDs (indicates what the outputs are doing even when no motor is connected)

• Robust:

  o Reverse-voltage protection to -16 V

  o Can survive input voltages up to 41 V

  o Undervoltage and overvoltage shutdown

  o High-side and low-side thermal shutdown

  o Short-to-ground and short-to-Vcc protection
