28 V Rated OVLO/UVLO Controller with Negative Stress Protection FPF2260ATMX Description FPF2260ATMX is an OVP and UVLO controller with reverse / www.onsemi.com negative voltage protection. The device controls and drives a pair of external NMOSFET that can operate over an input voltage range of 2.8 V to 23 V. In that way, with OVP feature implemented, the system can allow huge current as long as the external MOSFET can handle. When the input voltage exceeds the overvoltage threshold or lower than under voltage threshold, the external FET is turned off immediately to prevent damage to the protected downstream components. When the input voltage is stressed a negative voltage, the external FET will also be turned off and prevent OUT dropping to negative X2QFN12 1.6x1.6, 0.4P CASE 722AG voltage. FPF2260ATMX is available in a small X2QFN12 package and operate over the freeair temperature range of 40C to +85C.
