Im also connected the 4-wire bipolar motor with L293D driver. I tied all the 4inputs to the ground, and its corresponding output are all shown as Low. While im interfacing the motor with the IC, it got burnt. I dont know why it is happening. Two Ics were burnt. Please clarify me to solve the issue, and please help me to run the bipolar stepper motor.
And i doesnt have any specification for the motor, so i simple given to 24V to drive the motor. and IC operating voltage is 5V.
are you sure you don´t mix up those two VCC pins.
Without pin numbers we can´t check this.
If you only provide information that is in the datasheet we are not able to check what YOU really connected.
You keep your used pin numbers still as a secret.
