FP0100 Fault Protection Switch with Current Foldback Features • Up to ±100V Input Voltage Protection • 4Ω On-resistance, Typical • Fast-switching Speed • No External Supplies Needed • Available in a SOT-89 package Applications • Power Supplies • Fast Resettable Fuses • High-side Switches • Data Acquisition General Description 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. In Protection mode, the FP0100 limits the current to 300 µA. The FP0100 can be considered as a normally closed switch with a typical switch resistance of 4Ω. The peak current allowed to pass through the switch can be set by an external resistor across VOUT and RSEN.
