DRV8842PWP Frequently Asked Questions (FAQs)
The maximum voltage that can be applied to the VM pin is 40V, but it's recommended to keep it below 36V for reliable operation.
To configure the DRV8842PWP for a unipolar stepper motor, connect the motor coils between the AOUT and BOUT pins, and set the MODE pin to logic low. Also, make sure to set the current limit (ILIM) to a suitable value for your motor.
The EN (enable) pin is used to enable or disable the motor driver. When EN is high, the driver is enabled, and when EN is low, the driver is disabled. You can use the EN pin to control the motor's operation, for example, to turn the motor on or off.
The current limit (ILIM) can be set by connecting a resistor (RILIM) between the ILIM pin and GND. The value of RILIM determines the current limit. You can use the formula in the datasheet to calculate the required RILIM value for your motor's current rating.
The nFAULT pin is an open-drain output that indicates a fault condition, such as overcurrent, undervoltage, or overtemperature. You can connect a pull-up resistor to the nFAULT pin and monitor its state to detect faults. When a fault occurs, the nFAULT pin is pulled low.
