Part Number: DRV8311

Hi,

Good Day.

The customer wants to use the DRV8311. It's suitable for his application but small doubt in operating voltage.

DRV8311 Specification:

Operating Voltage = 3V-20V

Output Current = 5A peak

Max Voltage = 24V

Can he use this device continuously to 24V? What will happen?

Please advise. Thank you very much.

Best Regards,

Ray Vincent

Hi Vincent,

Continuously using the DRV8311 at 24 V can permanently break the device since 24 V exceeds the devices maximum rating.

TI recommends using a motor driver rated up to 1.2 × the maximum voltage for well-regulated supplies and low-power motors (<70 Watts), and 1.5 to 2 times for high-power motors (>70 watts) and battery systems.

Please refer to the Brushless-DC Motor Driver Considerations and Selection Guide app note for how to select the right motor driver for any application.

Best Regards,

Joshua
