General 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 spacesaving,
8-Lead, 3X3mm MLP.
