Description
The FPF2310/12/13/13L are dual-channel load switches
of IntelliMAX™ family. The FPF2310/12/13/13L consist
of dual, independent, current-limited, and slew rate
controlled, P-channel MOSFET power switches. Slew
rated turn-on prevent inrush current from glitching supply
rails. The input voltage range operates from 1.8V to 5.5V
to fulfill today's USB device supply requirements. Switch
control is accomplished by a logic input (ON) capable of
interfacing directly with low-voltage control signal.
For the FPF2312, if the constant current condition
persists after 10ms, these parts shut down the switch.
The FPF2310 has an auto-restart feature that turns the
switch on again after 150ms if the ON pin is still active.
FPF2313/13L remains in the constant-current mode until
the switch current falls below the current limit. For the
FPF2310 through FPF2313/13L, the minimum current
limit is 400mA-600mA with 10% accuracy (+25°C) for
each switch to comply with USB applications in portable
devices.
FPF2310M/12/13/13L series is available in a space-
saving, 8-Lead, 3X3mm MLP.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only.

Recommended Operating Range
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to absolute maximum ratings.
