Description of Operation
The FPF1003A is low RDS(ON) P-Channel load switches with controlled turn-on. The core of each device is a 30m P-Channel MOSFET and a controller capable of functioning over a wide input operating range of 1.2-5.5V. Switch control is by a logic input (ON) capable of interfacing directly with low voltage control signal.
Application Information
Typical Application
TO LOAD VIN Battery 1.2V-5.5V VOUT
FPF1003A OFF ON C1 = 1F ON GND C2 = 0.1F R1 = 499
Input Capacitor
To limit the voltage drop on the input supply caused by transient in-rush currents when the switch turns-on into a discharged load capacitor or short-circuit, a capacitor needs to be placed between VIN and GND. A 0.1F ceramic capacitor, CIN, must be placed close to the VIN pin. A higher value of CIN can be used to further reduce the voltage drop experienced as the switch is turned on into a large capacitive load.
Output Capacitor
A 0.1F capacitor, COUT, should be placed between VOUT and GND. This capacitor will prevent parasitic board inductance from forcing VOUT below GND when the switch turns-off. Due to the integral body diode in the PMOS switch, a CIN greater than COUT is highly recommended. A COUT greater than CIN can cause VOUT to exceed VIN when the system supply is removed. This could result in current flow through the body diode from VOUT to VIN.
Board Layout
For best performance, all traces should be as short as possible. To be most effective, the input and output capacitors should be placed close to the device to minimize the effects that parasitic trace inductances may have on normal and short-circuit operation. Using wide traces for VIN, VOUT and GND will help minimize the parasitic electrical effects along with minimizing the case to ambient thermal impedance.

ANTI-COUNTERFEITING POLICY Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Farichild'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 manufactures of semiconductor products are experiencing counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed application, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Farichild strongly encourages customers to purchase Farichild 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 handing and storage and provide access to Farichild's full range of up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address and warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Farichild is committed to 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.
