DATA SHEET www.onsemi.com AccuPower 0.4~2 A Adjustable Over-Current Protection Load Switches Top View Bottom View WDFN8 3x3, 0.65P MLP FPF2700, FPF2701, FPF2702 CASE 511DD Description The AccuPower FPF270X series is a family of currentlimit load switches that provide full protection to systems and loads from excess current conditions. Minimum current limit is adjustable from 0.4 A to Top View 2.0 A. The FPF270X contains a slewratecontrolled Nchannel SOIC8 SO8 MOSFET and slew rated turnon to prevent power bus disturbances CASE 751EB from being caused by hot plugging loads or momentary excess load demands. The input voltage range is 2.8 V to 36 V. Loads can be activated or deactivated with a lowvoltage logiccompatible ON pin. MARKING DIAGRAM Fault conditions can be monitored using the error flag pin and/or the powergood pin. Each member of the FPF270X family serves a category of Y&Z&2&K Y&Z&2&K loadfault response. All devices clamp the load current so that it FPF FPF cannot exceed an externally programmed current level. An over 270x 270x 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 WDFN8 SOIC8 fixed blanking period by turning off the load, followed by a retry after FPF270x = Device Code (x = 0, 1, 2) the autorestart time. Y = Logo FPF2701 responds to an overload condition that lasts longer than a &Z = Assembly Plant Code fixed blanking period by latching off the load. The load remains off &2 = 2Digit Date Code &K = 2Digits Lot Run Traceability Code unless either the ON pin is toggled or the input voltage cycles through UVLO. FPF2702 is intended to be used with external fault management. ORDERING INFORMATION Like the FPF2700 and FPF2701, it sets the fault signal pin LOW when See detailed ordering and shipping information on page 17 of it activates current clamping. This device is intended for applications this data sheet. where external fault management coordinates the overload response with the FPF2702. The FPF270X is available in a spacesaving, Lead and Halogen Applications free, 8lead, MLP 3x3 mm and SO8 packages.
