FPF2700/FPF2701/FPF2702-AccuPowerTM 0.4~2A Adjustable Over-Current Protection Load Switches
● Description:
■ The AccuPower™ FPF270X series is a family of current-limit load switches that provide full protection to systems and loads from excess current conditions. Minimum current limit is adjustable from 0.4A to 2.0A. The FPF270X contains a slew-rate-controlled N-channel MOSFET and slew-rated turn-on to prevent power bus disturbances from being caused by “hot plugging”loads or momentary excess load demands. The input voltage range is 2.8V to 36V. Loads can be activated or deactivated with a low-voltage logic-compatible ON pin. Fault conditions can be monitored using the error flag pin and/or the power-good pin.
■ Each member of the FPF270X family serves a category of load-fault response. All devices clamp the load current so that it cannot exceed an externally programmed current level. An over temperature feature provides further device protection in case of excessive levels of power dissipation.
■ FPF2700 responds to an overload condition that lasts longer than a fixed blanking period by turning off the load, followed by a retry after the auto-restart time.
■ FPF2701 responds to an overload condition that lasts longer than a fixed blanking period by latching off the load. The load remains off unless either the ON pin is toggled or the input voltage cycles through UVLO.
■ FPF2702 is intended to be used with external fault management. Like the FPF2700 and FPF2701, it sets the fault signal pin LOW when it activates current clamping. This device is intended for applications where external fault management coordinates the overload response with the FPF2702.
■ The FPF270X is available in a space-saving,Lead and Halogen free, 8-lead,MLP 3x3mm and SO8 packages.
