Hi,
we are using the above mentioned driver DRV8313 for driving three inductive loads. This works fine so far, but we have discovered an issue with the control signals.
Sometimes, the switching of the half-bridge does not start, when ENx is asserted before the PWM on INx starts. I searched in the datasheet for any advice of the sequence, in which the control signals shall be asserted. Can you please specify, in which order and with which timings the signals ENx, INx, nRESET and nSLEEP must be set.
We are using this driver in a safety relevant application, so we need to be sure that the driver is working correctly.
Thanks,
Andreas Arnold
