Description
The FPF2310/12/13/13L are dual-channel load switches of IntelliMAX family. T he 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-resta rt feature t hat 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 Figure 1. 8 Lead MLP (3x3mm)

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. Notes: 1. Soldered thermal pad on a two-layer PCB without vias based on JEDEC STD 51-3. 2. Soldered thermal pad on a four-layer PCB without vias connected with GND plane based on JEDEC STD51-5, 7. Recommended Operating Range The Recommended Operating Conditions table defines the conditions for actual dev ice operation. Recommended operating conditions are specified to ensure optimal perfor mance to the datasheet specifications. Fairchild does not recommend exceeding them or designing to absolute maximum ratings.

ANTI-COUNTERFEITING POLICY Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com, under Sales Support. Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are exp eriencing counterfeiting of their parts. Customers who inadvertently purchase counterfeit pa rts experience many problems such as loss of brand reputation, substandard performance, failed applications, and increased cost of production and manufact uring delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and wi ll appropriately address any warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors. Rev.
