onsemi FPF2700MX

The AccuPower™ FPF270X series are current-limiting load switches that provide comprehensive protection for systems and loads under overcurrent conditions. The minimum current limit is adjustable from 0.4 A to 2.0 A. The FPF270X incorporates a slew-rate-controlled N-channel MOSFET with controlled turn-on slew rate to prevent power bus disturbances caused by hot-plug loads or transient overload demands. The input voltage range is 2.8 V to 36 V. A low-voltage logic-compatible enable pin activates or disables the load. Fault status can be monitored via a fault flag pin and/or a power-good pin. Each device in the FPF270X series targets a specific load fault response category. All devices limit load current to an externally programmed level. An over-temperature protection feature provides additional protection at extremely high power dissipation levels. The FPF2700 responds to overload conditions exceeding a fixed blanking time by shutting off the load, then retrying after an auto-restart interval. The FPF2701 responds to overload conditions exceeding a fixed blanking time by shutting off the load. The load remains disconnected until the ON pin is toggled or the input voltage cycles through UVLO. The FPF2702 is designed for external fault management. Similar to the FPF2700 and FPF2701, it asserts the fault signal pin LOW when current clamping is activated. This device is intended for applications where external fault management coordinates the overload response of the FPF2702. The FPF270X is available in space-saving, lead-free and halogen-free 8-pin MLP3×3 mm and SO8 packages.
