Description
The FPF2310/12/13/13L are dual-channel load switches
of the 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 prevents inrush current from glitching
supply rails. The input voltage range operates from 1.8V
to 5.5V to fulfill USB device supply requirements. Switch
control is accomplished by a logic input (ON) capable of
interfacing directly with low-voltage control signals.
For the FPF2312, if the constant-current condition
persists after 10ms, the part shuts 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 constant-current mode until the
switch current falls below the current limit. For 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.
