Details about timings between the diagnosis signal
load current
Figure 15
In case of over-load as well as over-temperature, the voltage
diagnosis pins as long as the according input pin is high. This means, even if the
overload disappears after the first thermal shutdown or when the device keeps switching
on and off in over-load condition (thermal toggling), the diagnosis signal (
constantly available. Please refer to
overload disappears before the first thermal shutdown, the diagnosis signal (
may remain for approximately 300 μs longer than the duration of the overload.
As a result open load and over load including over temperature can be differentiated in
ON-state.
Consideration must be taken in the selection of the sense resistor in order to distinguish
nominal currents from the overload/short circuit fault state. A potential of 5 V at the sense
pin can be achieved with a big sense resistor even with currents being much smaller than
the current limitation.
