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 0.4 A to 2.0 A.

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 2.8 V to 36 V. 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

that

cannot

exceed

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 3x3 mm and SO8 packages.
