This is a placeholder topic for “VNH5019 Motor Driver Breakout” comments.



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.

Hi Core Electronics,

Is the current sensor on this board bi directional?

Thanks!

Hi Nicholas, Welcome to the forum,

Looking at the datasheet for the VNH5019 IC on that driver breakout it looks like it only measures the current output from the driver into the motor and cannot measure current going the other way in the event that a motor was acting as a generator.
