VNHD7012AY Evaluation Board

Hello everyone,

I'm looking for a Motor Driver IC and Motor Driver Evolution Board that can deliver 15 amps of continuous current. The VNHD7012AY Evaluation Board seems suitable for me, but will STM provide support in the future? Or are there any other driver development suggestions that would be comparable? In the meantime, I'll be driving the wiper motor.

Thanks in advance.

Welcome @ufukv, to the community!

Currently there are three devices able to drive your current, all of them automotive devices:

If you need support, you can either contact your local distributor, alternatively ask here in the public community or create a personal ticket at the Online Support OLS.

Does it answer your questions?

Hi Peter,

I'm so glad I joined the community and for the quick response.

This motor driver will actually be used in industrial area, but our motor is a 24V DC wiper motor. When I reviewed the products you recommend, they generally listed peak currents. The exact continuous current values ​​aren't listed. If the motor is obstacled phisically , it will consumes 15-18 amps. Can I trust this motor driver IC at this point?

 

Best Regards,

Ufuk

Peak current is not mentioned anywhere in the documetation of the H-Bridge drivers, but DC output current (continuous) is = Internally limited. It now depends on your layout whether you can dissipate the power loss and the resulting heat development under the target conditions (ambient temperature, air convection, etc.) so that the internal protection circuitry is not yet limiting.

All the types mentioned should be able to drive your 15...18A continuous current without any problems with a suitable design and layout.
