The NXP NX5P2190UKZ is a high-performance USB power switch designed to manage power distribution in portable and battery-operated devices. This advanced power switch is part of the NX5P series, which is renowned for its efficiency and reliability in protecting USB ports from overcurrent and short-circuit conditions.
Featuring a wide input voltage range of 2.8V to 5.5V, the NX5P2190UKZ is versatile enough to be used in a variety of applications. It can handle continuous current up to 2A, making it suitable for high-power USB devices and fast charging scenarios. This power switch also includes an under-voltage lockout (UVLO) feature that ensures stable operation even under fluctuating power conditions.
The NX5P2190UKZ is designed with a low on-resistance of just 70mΩ (typical), which minimizes voltage drop and power loss, ensuring that connected devices receive a stable and efficient power supply. Additionally, the device integrates over-temperature protection, which safeguards both the power switch and the USB port from thermal damage due to excessive current or ambient temperatures.
One of the key features of the NX5P2190UKZ is its fault reporting capability. The device provides a FLAG output that signals the host controller in the event of an overcurrent, short-circuit, or over-temperature condition, allowing for immediate response and system protection. Furthermore, this power switch is equipped with a controlled rise time to reduce inrush current, which is especially important for preventing damage when hot-plugging USB devices.
This USB power switch is available in a small, leadless HVSON10 package, measuring just 3mm x 3mm, making it ideal for space-constrained applications such as smartphones, tablets, and other portable electronics. With its robust protection features and compact design, the NXP NX5P2190UKZ is an essential component for any design requiring a safe and efficient USB power management solution.
