Sequence of events:

1-2) Current begins to rise

2) Current reaches IBUS_Trip level

2-3) Current is higher than IBUS_Trip for at least 6µs. This value is the worst-case condition with very low

over-current. In case of high current (short circuit), the actual delay will be smaller.

3-4) Delay between driver identification of over-current condition and disabling of all outputs

4) Current starts decreasing, eventually reaching 0

5) Current goes below IBUS_trip, the driver starts its auto-reset sequence

6) Driver is automatically reset and normal operation can resume (over-current condition must be removed

by the time the drivers automatically resets itself)

Note 5: The shaded area indicates that both high-side and low-side switches are off and therefore the half-bridge output

voltage would be determined by the direction of current flow in the load.
