NX30P0121UK
High-voltage back-to-back OVP switch

Product data sheet
General description
The NX30P0121UK is an advanced 3A unidirectional power switch. It includes
Undervoltage Lockout (UVLO), Overvoltage Lockout (OVLO) in VOUT, OVLO adjustable
pin and over-temperature protection circuits. It is designed to automatically isolate the
power switch terminals when a fault condition occurs. Both VIN and VOUT pins have 29V
tolerance in shutdown mode.
The device has a default internal 14.5V overvoltage protection threshold in VOUT and
adjustable OVP threshold by resistor divider from VOUT. ISNS pin is current source
output proportional to input current from VIN to VOUT when device is enabled.
The device is enabled by external EN pin. When EN pin is driven LOW, the device is in
shutdown mode where all internal circuitries are off and OVP switch is off. When EN pin
is driven HIGH and VIN is valid, the OVP switch soft starts after VIN debounce time to
limit the inrush current.
NX30P0121UK is offered in a small 12 bumps, 1.65 x 1.25 x 0.525 mm WLCSP package.

Switch ON mode
7.1 EN pin
When EN is driven LOW, the device enters shutdown mode regardless of VIN and VOUT
voltage. All internal circuitries are off to minimize current consumption and OVP switch
is OFF. When EN is driven HIGH, the OVP switch is ready to turn on depending on VIN
and VOUT condition. if VIN is above VINUVLO and VOUT is lower than VOUTOVLO, the
device soft starts after VIN debounce timer is expired, to reduce in-rush current. There is
an internal 1MΩ pull-down resistor in EN pin, which secure EN status in case EN pin is
float. This pin has +29V tolerance.
7.2 Undervoltage Lockout (UVLO)
When EN is driven HIGH and VIN < VINUVLO, the UVLO circuit disables the power
MOSFET. Once VIN exceeds VINUVLO and no other protection circuit is active, the
channel MOSFET state is controlled by the EN pin.
7.3 Overvoltage Lockout (OVLO)
When EN is driven HIGH and VOUT is above VOUTOVLO, the OVLO circuit disables
the power MOSFET within tdis(OVP). Once VOUT drops below VOUTOVLO and no other
protection circuit is active, the power MOSFET resumes operation.
OVLO pin is used to adjust the overvoltage protection threshold. The default overvoltage
threshold is 14.5V when OVLO pin is shorted to GND. Connecting a resistor divider to
the OVLO pin (see Figure 4) adjusts the overvoltage threshold from 4V to 20V using
below equation.
VOUTOVLO = Vth(OVLO) X ( R1 + R2 )/(R2)

threshold.

7.4 Over-temperature protection
When EN is HIGH and the device temperature exceeds 145°C the Over-Temperature
Protection (OTP) circuit disables the power MOSFET. Once the device temperature
decreases below 115 °C and no other protection circuit is active, the state of the OVP
MOSFET is controlled by the EN pin again.
7.5 ISNS pin
The ISNS pin is current source output having 1,053:1 ratio with input current from VIN
to VOUT. It requires a resistor from ISNS to GND to monitor input current. When device
is disabled, its output is high impedance. The ISNS voltage is determined by below
equation. RISNS is recommended to be +/-1% tolerant.
VISNS = ( IIN x RISNS ) / 1,053

Application diagram
The NX30P0121UK is typically used to add wireless charger path in single input
switching mode charger application. If wireless charger is used, then NX30P0121UK
bridge wireless charger output to the switching mode charger, protecting wireless charger
from up to 29V which could be from VBUS.
For best performance, it is recommended to keep input and output traces short and wide,
and capacitors as close to the device as possible. Regarding thermal performance, it is
recommended to increase the PCB area around VIN and VOUT pins.

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.
