Timing Diagrams
Figure 11 shows the timer behavior for LM5068-2, -4 during
fault re-try time. During normal operation, whenever the
SENSE pin exceeds the 50mV, circuit breaker fault limit, the
timer capacitor begins to charge. If the TIMER pin voltage
exceeds 4V, the GATE is pulled down immediately, and
LM5068-2, -4 disconnects power to the load. The TIMER
