NX18P3001
Bidirectional high-side power switch for charger and
USB-OTG combined applications
Rev. 1 — 24 September 2013
Product data sheet
1. General description
The NX18P3001 is an advanced bidirectional power switch and ESD- protection device
for combined USB-OTG and charger port applications. It includes undervoltage lockout,
overvoltage lockout and overtemperature protection circuits designed to automatically
isolate the power switch terminals when a fault condition occurs.
The device features two power switch input/output terminals (VBUSI and VBUSO), an
open-drain acknowledge output (ACK), an enable input which includes logic level
translation (EN) and low capacitance Transient Voltage Suppression (TVS) type ESD
clamps for USB data and ID pins.
When EN is set HIGH the device enters a low-power mode, disabling all protection
circuits. When used in combined charger and USB-OTG applications the 30 V tolerant
VBUSI switch terminal is used as the supply and switch input when charging, for
USB-OTG the VBUSO switch terminal is used as the supply and switch input.
Designed for operation from 3.2 V to 17.5 V, it is used in battery charging and power
domain isolation applications to reduce power dissipation and extend battery life.
