Applications
PDAs Cell Phones GPS Devices MP3 Players Digital Cameras Peripheral Ports Hot Swap Supplies RoHS Compliant General Description The FPF1005 & FPF1006 are low R DS P-Channel MOSFET load switches with CMOS cont rolled turn-on targeting small package load switch applications. The input voltage range operates from 1.2V to 5.5V. Switch control is by a logic input (ON) capable of interfacing directly with low voltage control signals. Optional on-chip load resistor is added for output quick discharge when switch is turned off. Both FPF1005 & FPF1006 are available in a small 2X2 MLP-6 pin plastic package.

7 www.fairchildsemi.comFPF1005-FPF1006 Rev.E FPF1005-FPF1006 IntelliMAXTM Advanced Load Management Products Description of Operation The FPF1005 & FPF1006 are low R DS(ON) P-Channel load switches with controlled turn- on. The core of each device is a 55mΩ P-Channel MOSFET and a controller capable of functioning over a wide input operating range of 1.2-5.5V. The ON pin, an active HI TTL compatible input, controls the state of the switch. The FPF1006 contains a 120 Ω on-chip load resistor for quick output discharge when the switch is turned off. However, V OUT pin of FPF1006 should not be connected directly to the battery source due to the discharge mechanism of the load switch.
Application Information
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 V IN and GND. A 1uF ceramic capacitor, C IN, placed close to the pins is usually sufficient. Higher values of C IN can be used to further reduce the voltage drop during higher current application. Output Capacitor A 0.1uF capacitor, C OUT, should be placed between V OUT and GND. This capacitor will prev ent parasitic board inductance from forcing VOUT below GND when the switch turns-off. Due to the integral body diode in the PMOS switch, a C IN greater than COUT is highly recommended. A C OUT greater than C IN 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 or large copper planes for all pins IN, V OUT, ON and GND) will help minimize the parasitic electrical effects along with minimizing the case to ambient thermal impedance.
