LT4356-3 APPLICATIONS INFORMATION The LT4356-3 can limit the voltage and current to the load circuitry during supply transients or overcurrent events. The total fault timer period should be set to ride through short overvoltage transients while not causing damage to ...
Page 11
APPLICATIONS INFORMATION Fault Timer Current The timer current starts at around 2μA with 0.5V or less increasing linearly to 50μA with 75V ing an overvoltage fault (Figure 1). During an overcurrent fault, it starts ...
