NX5P3001 Bidirectional high-side power switch for charger and USB-OTG applications Rev. 2.0 — 17 May 2023 Product data sheet 1 General description The NX5P3001 is an advanced bidirectional power switch and ESD-protection device for combined USBOTG 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. 2 Features and benefits 30 V tolerant VBUSI supply pin Wide supply voltage range from 3.2 V to 6.35 V Automatic switch operation for charging within the supply range ISW maximum 3 A continuous current Low ON resistance: 62 mΩ (typical) at a supply voltage o...
