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.
