NX3P1108
Logic controlled high-side power switch
Rev. 1 — 9 January 2013
Product data sheet
1. General description
The NX3P1108 is a high-side load switch which features a low ON resistance P-channel
MOSFET that supports more than 1.5 A of continuous current. It has an integrated output
discharge resistor to discharge the output capacitance when disabled. Designed for
operation from 0.9 V to 3.6 V, it is used in power domain isolation applications to reduce
power dissipation and extend battery life. The enable logic includes integrated logic level
translation making the device compatible with lower voltage processors and controllers.
The NX3P1108 is ideal for portable, battery operated applications due to low ground
current and ultra-low OFF-state current.
2. Features and benefits
Wide supply voltage range from 0.9 V to 3.6 V
Very low ON resistance:
34 m at a supply voltage of 3.3 V
High noise immunity
Low OFF-state leakage current (2.0 A maximum)
1.2 V control logic at a supply voltage of 3.6 V
High current handling capability (1.5 A continuous current)
Internal output discharge resistor
Turn-on slew rate limiting
ESD protection:
HBM JESD22-A114F Class 3A exceeds 4000 V
CDM AEC-Q100-011 revision B exceeds 500 V
Specified from 40 C to +85 C
3. Applications
Cell phone
Digital cameras and audio devices
Portable and battery-powered equipment

The (absolute) maximum power dissipation depends on the junction temperature Tj. Higher power dissipation is allowed in conjunction
with lower ambient temperatures. The conditions to determine the specified values are Tamb = 85 C and the use of a two layer PCB.

The overall Rth(j-a) can vary depending on the board layout. To minimize the effective Rth(j-a), all pins must have a solid connection to
larger Cu layer areas for example, to the power and ground layer. In multi-layer PCB applications, use the second layer to create a large
heat spreader area right below the device. If this layer is either ground or power, connect it with several vias to the top layer connected
to the device ground or supply. Try not to use any solder-stop varnish under the chip.
[2]
Rely on the measurement data given for a rough estimation of the Rth(j-a) in your application. The actual Rth(j-a) value may vary in
applications using different layer stacks and layouts

Product data sheet
Suitability for use — NXP Semiconductors products are not designed,
authorized or warranted to be suitable for use in life support, life-critical or
safety-critical systems or equipment, nor in applications where failure or
malfunction of an NXP Semiconductors product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. NXP Semiconductors and its suppliers accept no liability for
inclusion and/or use of NXP Semiconductors products in such equipment or
applications and therefore such inclusion and/or use is at the customer’s own
risk.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. NXP Semiconductors makes no
representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and operation of their applications
and products using NXP Semiconductors products, and NXP Semiconductors
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the NXP
Semiconductors product is suitable and fit for the customer’s applications and
products planned, as well as for the planned application and use of
customer’s third party customer(s). Customers should provide appropriate
design and operating safeguards to minimize the risks associated with their
applications and products.
NXP Semiconductors does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default in the
customer’s applications or products, or the application or use by customer’s
third party customer(s). Customer is responsible for doing all necessary
testing for the customer’s applications and products using NXP
Semiconductors products in order to avoid a default of the applications and
the products or of the application or use by customer’s third party
customer(s). NXP does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those given in
the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
Terms and conditions of commercial sale — NXP Semiconductors
products are sold subject to the general terms and conditions of commercial
sale, as published at http://www.nxp.com/profile/terms, unless otherwise
agreed in a valid written individual agreement. In case an individual
agreement is concluded only the terms and conditions of the respective
agreement shall apply. NXP Semiconductors hereby expressly objects to
applying the customer’s general terms and conditions with regard to the
purchase of NXP Semiconductors products by customer.
No offer to sell or license — Nothing in this document may be interpreted or
construed as an offer to sell products that is open for acceptance or the grant,
conveyance or implication of any license under any copyrights, patents or
other industrial or intellectual property rights.
