The NXP NX5P3090UK is a high-performance power switch designed for USB applications. This advanced device is tailored to manage power distribution and protection in portable and compact electronics, ensuring devices operate safely and efficiently.

Key Features

• Current Limiting: The NX5P3090UK offers a precise current limiting function, which protects the USB port by preventing excessive current from flowing through, which could otherwise damage sensitive electronics.
• Over-Temperature Protection: With an integrated temperature sensor, the power switch automatically shuts down the power if the temperature exceeds safe operating conditions, thereby safeguarding the device from thermal damage.
• Reverse Current Blocking: This feature prevents current from flowing backward into the source when the switch is off, which is critical for preventing power drain and potential damage to upstream devices.
• High-Side Switch: As a high-side switch, the NX5P3090UK allows for seamless power distribution control, enabling or disabling power to downstream components without interrupting the ground connection.

Technical Specifications

• Operating Voltage: The device operates within a voltage range of 2.8V to 5.5V, making it suitable for a variety of USB-powered applications.
• Switch On-Resistance: It features a low on-resistance of typically 70 mΩ, ensuring minimal voltage drop and power loss across the switch.
• Switch Current Capability: The power switch can handle continuous current up to 2A, accommodating most USB peripherals and devices.
• Package: The NX5P3090UK comes in a compact WLCSP6 package, which is ideal for space-constrained applications.

Applications

The NXP NX5P3090UK is versatile and can be used in a range of applications, including smartphones, tablets, cameras, and other portable electronic devices that require reliable power management and distribution. Its robust protection features make it an indispensable component in any USB interface power design.
