APPLICATIONS INFORMATION
Fault Timer Current
The timer current starts at around 2μA with 0.5V or less
of V DS , increasing linearly to 50μA with 75V of V DS dur-
ing an overvoltage fault (Figure 1). During an overcurrent
fault, it starts at 4μA with 0.5V or less of V DS but increases
to 260μA with 80V across the MOSFET (Figure 2). This
arrangement allows the pass transistor to turn off faster
When the voltage at the TMR pin, V TMR , reaches the 1.25V
threshold, the FLT pin pulls low to indicate the detection
of a fault condition and provide warning to the load of
the impending power loss. In the case of an overvoltage
fault, the timer current then switches to a ?xed 5μA. The
interval between FLT asserting low and the MOSFET turn-
ing off is given by:
during an overcurrent event, since more power is dissipated
during this condition. Refer to the Typical Performance
Characteristics section for the timer current at different
V DS in both overvoltage and overcurrent events.
