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
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

General Description
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.
The FPF1016 and FPF1018 have an On-Chip pull down
allowing for quick and controlled output discharge when switch
is turned off. The FPF1015/6/7/8 series is available in a
space-saving 2X2 MLP-6L package.

FPF1015/6/7/8 IntelliMAXTM 1V Rated Advanced Load Management Products
Description of Operation
The FPF1015/6/7/8 are low RDS(ON) N-Channel load switches
with controlled turn-on. The core of each device is a 34mΩ
(VIN = 1V, VON = 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 60Ω(typ) on-chip resistor
which is connected internally from VOUT 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 ≥ VON ≥
VIN+2V and power consumed is less than 1µA in steady state.

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, 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.
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.
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
(VIN, VOUT
, ON and GND) will help minimize the parasitic
electrical effects along with minimizing the case to ambient
thermal impedance.

Improving Thermal Performance
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.
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.
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.
