FPF2312: Dual Output Adjustable Current Limit Switch

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 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 signal. 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 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.
