In contrast to Figure 10.1 in where the overload situation stops at the point in time in which the driver has been

locked Figure 10.2 shows a situation in which the overload situation, especially an over-current situation is kept.

This situation occurs for instance due to a low impedance load which is permanently interconnected to the driver

output. In addition to that the lock reset is configured in that way that its period is significantly shorter compared

with the assert time period. In this case the overload counter does not reach the zero value at the point in time the

lock is reset. This in the following time the assert time is shortened and equals approximately the lock time that

even passed by.
