Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated

General Description
0.8 to 1.8V Input Voltage Range
The FPF1015/6/7/8 series is an IntelliMAX advanced slew rate
loadswitch offering a very low operating voltage. These devices
consist of a 34mΩ N-channel MOSFET that supports an input
voltage up to 2.0V. These slew rate devices control the switch
turn-on and prevent excessive in-rush current from the supply
rails. The input voltage range operates from 0.8V to 1.8V to
fulfill today's lowest Ultraportable Device's supply requirements.
Switch control is via a logic input (ON) capable of interfacing
directly with low voltage control signals.

a low input operating range of 0.8 to 1.8V. The ON pin controls

Applying a continuous high signal will hold the switch in the ON

compatible with a GPIO (General Purpose Input/Output) port,

Input Capacitor
Board Layout
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 VIN 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 VIN pins. Higher
values of CIN can be used to further reduce the voltage drop
during higher current modes of operation.
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
(VIN, VOUT, ON and GND) will help minimize the parasitic
electrical effects along with minimizing the case to ambient
thermal impedance.
Output Capacitor
A 0.1µF capacitor, CL, should be placed between VOUT and
GND. This capacitor will prevent parasitic board inductance
from forcing VOUT 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.

Description of Operation
Demo Board Layout
An improper layout could result in higher junction temperature.
This concern applies when the current is at its continuous
maximum value and is then switched into a large capacitive
load that introduces a large transient current. Since the
FPF1015/6/7/8 does not have thermal shutdown capability, a
proper layout is essential to improving power dissipation of the
switch in transient events and prevents the switch from
exceeding the maximum absolute power dissipation of 1.2W.
FPF1015/6/7/8 Demo board has the components and circuitry
to demonstrate FPF1015/6/7/8 load switches functions.
Thermal performance of the board is improved using a few
techniques recommended in the layout recommendations
section of datasheet.
The following techniques have been identified to improve the
thermal performance of this family of devices. These techniques
are listed in order of the significance of their impact.
1. Thermal performance of the load switch can be improved by
connecting pin7 of the DAP (Die Attach Pad) to the GND plane
of the PCB.
2. Embedding two exposed through-hole vias into the DAP
(pin7) provides a path for heat to transfer to the back GND
plane of the PCB. A drill size of Round, 14 mils (0.35mm) with
1-ounce copper plating is recommended to result in appropriate
solder reflow. A smaller size hole prevents the solder from
penetrating into the via, resulting in device lift-up. Similarly, a
larger via-hole consumes excessive solder, and may result in
voiding of the DAP.

and DRL layers
1 4 M il
1 5 M il
Figure 19: Two through hole open vias embedded in DAP
3. The VIN, VOUT and GND pins will dissipate most of the heat
generated during a high load current condition. The layout
suggested in Figure 20 provides each pin with adequate copper
so that heat may be transferred as efficiently as possible out of
the device. The ON pin trace may be laid-out diagonally from
the device to maximize the area available to the ground pad.
Placing the input and output capacitors as close to the device as
possible also contributes to heat dissipation, particularly during
high load currents.
