Microchip Technology FP0100
The FP0100 is a high-voltage Fault protection switch with current foldback. It is designed to protect system output power supplies against Overcurrent and Short-circuit conditions. The FP0100 can be considered as a normally closed switch with a typical switch resistance of 4Ω.| Part No. | FP0100 |

GENERAL DESCRIPTION
In Protection mode, the FP0100 limits the current to 300 µA. 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 3V, the input current will foldback to 300 µA. In the OFF state, the FP0100 can withstand up to 100V. Higher input voltages can be accommodated using an external Depletion-mode MOSFET. Refer to Figure 3-3 for more details.
