If the driver has entered the error state, it must be reset before the driver resumes to operation mode. The
driver could be reset under the following conditions:
•
>30µs non-error condition (Reaction on customer side should happen within that time)
•
>9µs no input signals at TOP_IN/BOT_IN (Customer confirms error)
After completing the reset sequence the driver returns ‘ready for operation’ by setting the nERR_OUT
output to high-level.
If the driver has entered error state because of an externally reported error event by the controller via the
driver’s primary side nERR_IN pin, the driver can be reset under the following conditions:
•
> 30µs has elapsed until the external error event occurred
•
> 9µs no input signals at TOP_IN/BOT_IN
Important note
In this particular case the driver is ready for operation again, if the nERR_OUT output is set to high-level by
the driver and the external error signal is removed. This behavior prevents deadlock situations, if several
drivers are using the bi-directional HALT feature, as described in chapter 4.7.
