Hi All,
I'm Developing a product to drive the BLDC Fan using DRV8313. I bought DRV8313EVM and been exploring it for a while. i want to realize it on the product, but I've got some queries before i do that. Please clarify.
1) There is already inbuilt OCP in the device, therefore, i think, external IDC current sensing through a resistor is not necessary. Is it right?
2) Can I connect nFAULT to nRESET, means, if a fault occurs due to Over Current Protection feature or Over Temperature Protection feature or UVLO feature, the nFAULT goes LOW pulling down nRESET there by disabling the device outputs.Once the faults get cleared then nFAULT floats releasing nRESET there by allowing the device to output the required channels.
3) Can I keep SLEEP pin pulled up by a 47k to 3.3V ?
Or can I leave this pin floating?
I do not want to use this feature at all as it is not required in my product.

4) Can we always keep the pins EN1,EN2 & EN3 pulled up by a 47k to 3.3V ?
By this I would want to Enable all the PWM signals to IN1, IN2 & IN3. Is it possible?
Thanks in Advance. :)
