1. General description
The NX5P3001 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 6.35 V, it is used in battery charging and power
domain isolation applications to reduce power dissipation and extend battery life.
