Description of Operation
Timing Diagram
The FPF1015/6/7/8 are low R DS(ON) N-Channel load switches
with controlled turn-on. The core of each device is a 34m ?
(V IN = 1V, V ON = 3V) N-Channel MOSFET and is customized for
a low input operating range of 0.8 to 1.8V. The ON pin controls

the state of the switch.
The FPF1016 and FPF1018 contain a 60 ? (typ) on-chip resistor

which is connected internally from V OUT to GND for quick output
discharge when the switch is turned off.
On/Off Control
The ON pin is active high and it controls the state of the switch.

Applying a continuous high signal will hold the switch in the ON
state. In order to minimize the switch on resistance, the ON pin
voltage should exceed the input voltage by 2V. This device is
compatible with a GPIO (General Purpose Input/Output) port,
where the logic voltage level can be configured to 4V ≥ V ON ≥
V IN +2V and power consumed is less than 1μA in steady state.

Input Capacitor
To limit the voltage drop on the input supply caused by transient
in-rush currents when the switch turns-on, a capacitor must be
placed between V IN and GND. For minimized voltage drop,
especially when the operating voltage approaches 1V and a fast
slew rate part (FPF1015 and FPF1016) is selected, a 10μF
ceramic capacitor should be placed close to the V IN pins. Higher
values of C IN can be used to further reduce the voltage drop
during higher current modes of operation.
Output Capacitor
A 0.1μF capacitor, C L , should be placed between V OUT and
GND. This capacitor will prevent parasitic board inductance
from forcing V OUT below GND when the switch turns-off. If the
application has a capacitive load, the FPF1016 and FPF1018
can be used to discharged that load through an on-chip output
discharge path.
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
(V IN , V OUT , ON and GND) will help minimize the parasitic
electrical effects along with minimizing the case to ambient
thermal impedance.
