Are currently TI drivers available to connect three brushed motors in the 48V system?

Hi,

I understood you do not have TI sales contact. Never mind.

DRV8962-Q1 has independent mode so can control each OUTPUT separately.

Your configuration could be possible.

I tried with the DRV8706-q1 in the 12V to independently control the bridges but didn't get the desired results.

Talking related toDRV8962-q1, is it Possible to connect three motors with specs (1A steady current and 3.45 stalling current) using this driver?

Hi,

I am assuming only one motor spin at the same time. If stall 3.45A period is ~up to 1sec, should be OK.

yes, you are correct, I forgot to mention.

Can this driver ASIL B compliant?

No, This device itself is not ASIL-B compliant device.

TI has Function safety category like this link, but this device is not supporting these.
