Frequently Asked Questions
What is the operational supply voltage range for this motor driver?
The operating supply voltage (Vcc) ranges from 4.5 V to 17.0 V.
How should I prevent damage during overvoltage conditions?
If you expect to exceed absolute maximum ratings, such as the supply voltage, consider adding circuit protection devices like fuses.
Can this device handle high electromagnetic vibrations?
The product is not designed for production against radioactive rays. Use careful thermal and electrical design safety measures in your equipment.
What precaution should be taken concerning ground (GND) potential?
Ensure that the GND pin maintains minimum potential, and all other terminals do not fall below GND voltage due to back electromotive force or transients.
