Supertex inc. FP0100 Fault Protection Switch with Current Fold-back Features ►► Up to 100V input voltage protection ►► Low on resistance – 4.0Ω typical ►► Fast switching speed ►► No external supplies needed Applications ►► Power supplies ►► Fast resettable fuse ►► High side switches ►► Data acquisition 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.
