Battery Chargers
Battery management products are total power
management ICs (TPMICs) that manage the charging,
sequencing, and protection of lithium-ion/polymer
batteries in personal portable electronics. Skyworks’
linear and switching chargers are designed for single and/
or dual cell lithium-ion/polymer batteries. These fullfeatured battery management ICs maximize charging
speed and minimize power loss during power delivery
to the system. Additionally, they offer integrated system
protection using USB and/or adaptor input and dynamic
charging capabilities. Many of these products contain
unique circuit features to provide advanced IC thermal
management during charging and proprietary input
power control when supplied from USB port sources.
New additions to this product line also feature over
voltage protection up to 28 V.
Linear Chargers
Skyworks’ linear chargers are designed for single and dual
cell lithium-ion/polymer batteries and offer an attractive,
low-cost, low noise solution. These full-featured battery
management ICs provide multiple levels of power savings,
with system protection integrated inside along with
single path, dual path, and dynamic charging capabilities.
Electrical specifications are shown in Table 1.
Switching Chargers
Linear charger ICs commonly used today to charge singlecell lithium-ion batteries offer an attractive, low-cost, low
noise solution, but they can’t deliver the higher efficiency
levels needed to support higher charge rates and shorter
charging cycles. Switching chargers, on the other hand,
offer dramatically improved efficiency and higher charge
rates. By using the best of both charging methodologies,
Skyworks’ switching chargers offer portable system
designers a new way to quickly charge a new generation
of higher capacity batteries while minimizing the
inherent noise of switch-mode power supplies. Electrical
specifications are shown in Table 2.

Supercap Chargers
Skyworks supercap chargers are programmed, current
limited P-channel metal-oxide-semiconductor field-effect
transistor (MOSFET) power switches designed for high-side
load-switching applications, such as solid-state drive (SSD)
memory buffer saving. With programmed current limits,
these devices ensure that the power ratings of the host
are not exceeded, balancing the system load and supercap
charging current automatically to provide enough system
load current in top-priority. The integrated discharge path
control assures that the system load can still be supported
in the short term when the input power has not fully
charged the supercap. The current limit is programmed
by an external resistor allowing ±10% accuracy at room
temperature. Electrical specifications are shown in Table 3.
DC/DC Converters (Switching Regulators)
Skyworks’ high efficiency pulse width modulation (PWM)
switch-mode voltage regulators are ideal for a wide
variety of products such as smartphones, PNDs, notebook
computers, set-top boxes, digital still cameras, and other
portable electronic devices. Solutions are available for
a wide range of output power, optimizing both size
and performance for specific power levels. The switchmode products utilize high switching frequencies to
minimize output inductor and capacitor size. Internal
compensation eliminates additional external components.
These products provide excellent light load efficiency
and minimum light load ripple. In addition to excellent
efficiency, many SwitchReg™ products offer fast turnon time and fast transient response capabilities. Taking
advantage of advanced modular bipolar CMOS DMOS
(BCD) processes allows very low resistance switches and
eliminates the need for special packages that require
additional thermal relief.
Step-up Converters
Step-up converter solutions are available for a wide range
of output power, optimizing both size and performance
for specific power levels. The switch-mode products
utilize high switching frequencies to minimize output
inductor and capacitor size. These devices are available
in fixed and adjustable outputs and are designed to be
stable with both ceramic and titanium output capacitors.
Other standard features include over-current, overtemperature, on/off enable, and power good indicator
circuits. Electrical specifications are shown in Table 4.
Step-down Converters
Step-down converter solutions are available for a
wide range of output power, optimizing both size and
performance for specific power levels. The switch-mode
products utilize high switching frequencies to minimize
output inductor and capacitor size. These devices are
available in fixed and adjustable outputs and are designed
to be stable with both ceramic and titanium output
capacitors. Other standard features include over-current,
over-temperature, on/off enable, and power good
indicator circuits. Electrical specifications are shown in
Table 5.
Low Drop-out (LDO) Linear Regulators
Linear voltage regulators (PowerLinear™) products
include MicroPower™, NanoPower™, and OmniPower™
LDO linear regulators which provide regulated power
sources in products such as smartphones, PNDs,
notebook computers, set-top boxes, digital still cameras,
and other portable personal electronic devices. Skyworks’
LDO regulator products are designed to provide a well
regulated power supply while at the same time maximize
the performance for a given application. NanoPower™
LDO regulators typically operate with a ground current
level of 1.1 µA. The MicroPower™ product line has LDO
regulators optimized for low output noise and high
power supply ripple rejection, making them well suited
for sensitive RF and wireless circuit applications. Other
MicroPower™ single- and dual-channel LDO regulators
from Skyworks feature fast transient response to meet
the most demanding load requirements. OmniPower™
LDO regulators are suitable for general purpose
linear regulation requirements across a wide range of
applications. All Skyworks LDO regulators are designed
to be highly reliable and stable over a wide range of
operating conditions.
In addition, LDO regulator devices function with a wide
variety of input and output capacitor types. However,
they are ideally suited for stability with ceramic capacitors.
Low-cost ceramic capacitors are recommended to help
increase circuit performance, reduce printed circuit
board area, and minimize cost. To further enhance
application reliability under adverse operating conditions,
all PowerLinear™ LDO regulators include over-current
and over-temperature protection circuits. Electrical
specifications are shown in Table 6.
Display and Lighting
Lighting Management Units
Given the complexity and diversity of feature sets found
in today’s smartphones, designers can gain tremendous
advantage in terms of design time and cost by using
Skyworks’s lighting management unit (LMU) solutions.
These devices drive multiple LEDs as well as integrate
multiple LDOs linear regulators. Optimized for singlecell lithium-ion/polymer powered systems, the unique
capabilities of these devices make them ideal for I2Cbased high performance smartphones and other mobile
devices. LMUs also add an automatic fade-in/fade-out
backlight control that simplifies design and reduces
processor overhead. Electrical specifications are shown in
Table 7.
RGB LED Controllers
These SmartSwitch™ devices are members of the
Application Specific Power MOSFET™ (ASPM™) product
family. They are intended for controlling RGB fashion
lighting in portable products and operate with an input
voltage ranging from 1.8 V to 5.5 V, making them ideal
for 2.5 V, 3.3 V, or 5 V systems. They can also be used for
a combination of general purposes where a load requires
a low-side switch connection to ground.
These devices simplify design and layout limitations
by eliminating the need for multiple general-purpose
input/output (GPIO) control lines and discrete MOSFETs
to control product features. To simplify switch
implementation and reduce pin count, the state of each
output channel is controlled with a single GPIO via the
EN/SET pin using Simple Serial Control™ (S2Cwire™)
one-wire interface. Electrical specifications are shown in
Table 8.

White LED Drivers
Skyworks offers a wide array of innovative solutions
for white LED backlighting including regulated voltage
output charge pumps and regulated current output
charge pumps. Regulated voltage charge pumps are ideal
for use in low-cost LCD panel backlighting applications.
Regulated current charge pumps provide constant current
source or sink outputs to drive white LEDs. By providing
constant current to a white LED, uniform brightness
can be assured across an array of white LEDs regardless
of variations in the LED forward voltage. Products in
this device family use single and multiple fractional
charge pump topologies to maximize voltage conversion
efficiency from lithium-ion/polymer batter sources.
Electrical specifications are shown in Table 9.
Port Protection and Power Distribution
Multi-function Power Management
Integrated Circuit (PMIC/PMU)
Single Input High Side Switches / Current Limiters
These devices are highly integrated system power
management units offering a wide combination of
step-up charge pump regulators, step-up and step
down switching regulators, and low drop out regulators.
Electrical specifications are shown in Table 10.
Power Half Bridges
Skyworks’ power half bridges include multiMHz power
switches that can be used to provide compact voltage
regulation in high-speed power supplies. Integrating input
level shifting, high-speed break-before-make (shootthrough protection) circuitry, and low resistance, these
power MOSFETs reduce board space, parts count, and
stray parasitics in switching power supplies. FastSwitch™
buffered half bridge products may be used to drive
inductors directly, as high-current gate drivers for discrete
power MOSFETs. In addition, a dual buffered halfbridge may be used to drive multiple outputs or can be
configured as a full bridge to affect a DC motor or Class-D
audio driver. Electrical specifications are shown in Table 11.

Current Limited Load Switches (USB PCMCIA)
Current Limited Load Switches are designed for high-side
power switching applications to cover a wide range of
port protection applications for USB, PCMCIA
(PC cards), and IEEE 1394 (FireWire) ports in desktop
and notebook computers. Port protection switches
provide inrush current limiting, short-circuit and overtemperature protection, input control level shifting, and
fault flags. Designers can select different current limit
options from preset thresholds to user-adjustable limits
using just one external resistor. Single, dual, and quad
switches are available to fulfill a wide array of application
requirements. Devices intended for USB applications have
complete Underwriters Laboratories® approval.
These SmartSwitch™ devices are members of the
Application Specific Power MOSFET™ (ASPM™) product
family. The devices are available in a number of channel
configurations and have an integrated current-limiting
circuit to protect the input supply against large changes
in load current which could cause the supply to fall out of
regulation. Electrical specifications are shown in Table 12.
I/O Expander Serial Controlled Load Switches
These SmartSwitch™ devices are members of Skyworks’
Application Specific Power MOSFET™ (ASPM™) product
family. They are targeted for I/O expansion applications
and operate with an input voltage ranging from 1.8 V to
5.5 V, making them ideal for 2.5 V, 3.3 V, or 5 V systems,
as well as systems powered by lithium-ion batteries. These
devices can also be used for general purpose power load
switching.
To simplify switch implementation and reduce pin
count, the state of each output channel is controlled
with a single GPIO via the EN/SET pin using Skyworks’
Simple Serial Control™ (S²Cwire™) one-wire interface.
These devices have very low quiescent supply current
significantly improving power efficiency. Electrical
specifications are shown in Table 13.
Over Voltage Protection
Skyworks’ over-voltage protection (OVP) switches provide
up to 28 V over-voltage and overcurrent protection when
powering low-voltage systems such as cell phones, MP3,
and PDAs or when charging Lithium Ion batteries from a
badly regulated supply.
These devices are inserted between the power supply or
charger source and the load to be protected. The devices
consist of a low resistance OVP switch, under-voltage
lockout protection, over-voltage monitor and protection,
over-current protection, battery over-voltage protection,
fast shut-down circuitry, and a fault output flag. In normal
operation the OVP switch acts as a slew-rate controlled load
switch, connecting and disconnecting the power supply
from IN to OUT. A low resistance N channel MOSFET is used
to minimize the voltage drop between the voltage source
and the load and to reduce the power dissipation.
When the voltage on the input exceeds the programmed
over-voltage trip point, the device immediately turns off
the internal OVP switch disconnecting the load from the
abnormal voltage, preventing damage to any downstream
components. In the case of an over-current condition, it
limits the system current at the threshold value, and if the
over current persists, the OVP switch is turned off after a
blanking period. If the battery voltage rises to an unsafe
level battery over-voltage protection (BOVP) threshold, the
IC disconnects OUT from the charging input power IN until
the battery voltage returns to an acceptable value. BOVP
or over-current protection (OCP) blanking time ignores
short-time transients of over-battery voltage and overload
current. Additionally, these devices also monitor their own
die temperature and turn the OVP switch off if it becomes
too hot. Electrical specifications are shown in Table 14.
Slew Rate Controlled
These SmartSwitch™ devices are members of the
Application Specific Power MOSFET™ (ASPM™) product
family. They are intended for high-side load-switching
applications and operate with an input voltage ranging
from 1.8 V to 5.5 V, making them ideal for 2.5 V, 3.3 V,
or 5 V systems. These devices have low RDS(ON), allowing
a low forward voltage drop and high current handling
capability. Electrical specifications are shown in Table 15.
Supervisors/Monitors, Voltage Detectors –
Microprocessors
The microprocessor supervisor product line offers
significant enhancements to Skyworks’ standard voltage
detectors. These devices provide a variety of additional
user-selectable options beyond simple power-on or lowvoltage reset functions. Selectable enhanced features may
include reset delay functions, manual reset capabilities,
and watchdog timers. Microprocessor supervisor devices
are commonly used in notebook computers, cellular
telephones, portable electronic products, and embedded
systems. Electrical specifications are shown in Table 16.
