Overview

FP0100N8-G 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 FP0100N8-G limits the current to 300µA.The FP0100N8-G 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 FP0100N8-G 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 FP0100N8-G is available in a SOT-89 package.
