Description
The FPF1107/08 are low R DS P-channel MOSFET load switches of the IntelliMAX™ family. Integrated slew-rate control prevents inrush current from glitch supply rails with capacitive loads common in power applications. The input voltage range operates from 1.2V to 4V to fulfill today's lowest ultra-portable device supply requirements. Switch control is by a logic input (ON-pin) capable of interfacing directly with low-voltage CMOS control signals and GPIOs in embedded processors.

Application Information
The IntelliMAXTM switch doesn’t require input capacitor. To reduce device inrush current effect, a 0.1µF ceramic capacitor, CIN, is recommended close to the VIN pin. A higher value of C IN can be used to further reduce the voltage drop experienced as the switch is turned on into a large capacitive load. Output Capacitor The IntelliMAX TM switch works without an output capacitor. However, if parasitic board inductance forces VOUT below GND when switching off, a 0.1µF capacitor, COUT, should be placed between VOUT and GND. Fall Time Device output fall time can be calculated based on RC constant of external components as follows: 2.2CRt LLF ××= (1) where tF is 90% to 10% fall time, R L is output load and CL is output capacitor. The same equation works for a device with a pull-down output resistor, then R L is replaced by a parallel connected pull-down and external output resistor combination, as follows: 2.2CRR RRt L PDL PDL F ××+ ×= (2) where t F is 90% to 10% fall time, R L is output load, RPD=65Ω is output pull-down resistor, and C L is the output capacitor. Resistive Output Load If resistive output load is missing, the IntelliMAX TM switch without pull-down output resistor is not discharging output voltage. Output voltage drop depends, in that case, mainly on external device leaks.
