FPF1005-FPF1006 Rev. G
Description of Operation
The FPF1005 & FPF1006 are low R
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 120Ω on-chip load resistor
for quick output discharge when the switch is turned off.
However, V
directly to the battery source due to the discharge mechanism of
the load switch.
Application Information
Typical Application
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 V
close to the pins is usually sufficient. Higher values of C
be used to further reduce the voltage drop during higher current
application.

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
