Figure 25 Overload Current Thresholds variation with TJ
Power supply voltage VS can increase above 18 V for short time, for instance in Load Dump or in Jump Start
condition. Whenever VS ≥ VS(JS), the overload detection current is set to IL(OVL_JS) as shown in Figure 26.

When IL ≥ IL(OVL) (either IL(OVL0), IL(OVL1) or IL(OVL_JS)), the channel is switched OFF. The channel is allowed to restart
according to the retry strategy described in Chapter 8.3.
