General Description
The Supertex FP0100 is a high voltage fault protection switch
with current fold-back. It is designed to protect system output
power supplies against over-current or short circuit conditions.
In protection mode, the FP0100 limits the current to 300µA.
The FP0100 can be considered as a normally closed switch
with a typical switch resistance of 4.0Ω. The peak current
allowed to pass through the switch can be set by an external
resistor across VOUT and RSEN. Once the voltage drop
across VIN and VOUT exceeds a nominal value of 3.0V,
the input current will fold-back to 300µA. In the off state, the
FP0100 can withstand up to 100V. Higher input voltages
can be accommodated by using an external depletion-mode
MOSFET. Please refer to Figure 4 for more details. The
FP0100 is available in a SOT-89 package.

The input peak current, IPEAK, can be lowered by adding an
external resistor across the RSEN and VOUT pins as shown
in the test circuit in Figure 2. IPEAK will decrease as the resis-
tor value of RSEN increases. The typical IPEAK vs RSEN charac-
teristic is shown in Figure 3.
