Hi,

For our Medical Respirator equipment, We need Micro controller, Which is capable of controlling BLDC motor up to 60,000 RPM with minimum CPU utilization.

Please suggest suitable microcontroller from ST.

Thanks

Dear Kannan

the L6235 and L6229 are fully integrated BLDC motor drivers which does not require any load on the MCU (if you perform the speed control loop using an op-amp).

The speed limit is more related to the maximum current you can obtain from the power stage according to the supply voltage.

ST provides different evaluation boards you can you to check if the device fits your requirements.

Regards

Enrico

I suggest evaluating STM8A product family and 32-bit Power Architectureâ„¢ based SPC5 product family.

All products are automotive qualified.
