Maxim Integrated MAX4995AFAUT+T

The MAX4995AFAUT+T from Maxim Integrated is a high-performance, programmable current limiter designed to provide an efficient solution for USB port protection and other hot-swap applications. This device is part of Maxim's extensive range of power management integrated circuits, known for their reliability and precision.

Featuring an adjustable current-limit threshold from 100mA to 1A, the MAX4995AFAUT+T allows designers to tailor the protection to the needs of their specific application. The current limit can be set with an external resistor, providing flexibility and ease of use. This versatility makes it an ideal choice for protecting USB ports, which can be subjected to various electrical stresses such as short circuits or excessive current draw from connected devices.

The MAX4995AFAUT+T operates over a wide supply voltage range from 2.7V to 5.5V, making it suitable for low-voltage USB applications as well as other portable and battery-powered devices. Its low quiescent current ensures minimal power consumption when in operation, which is crucial for extending battery life in portable applications.

This device also features thermal shutdown protection, which provides additional safety by turning off the current path if the die temperature exceeds a safe threshold. This helps prevent damage to both the MAX4995AFAUT+T itself and the protected downstream circuits. Once the device cools down, it will automatically attempt to restart, ensuring continuous protection without the need for user intervention.

The MAX4995AFAUT+T comes in a compact, 8-pin µDFN package, which is ideal for space-constrained applications. Its small footprint and low profile make it easy to integrate into modern, compact electronic designs without compromising performance.

With its combination of adjustable current limiting, wide operating voltage range, low power consumption, and thermal protection, the MAX4995AFAUT+T from Maxim Integrated is a robust solution for circuit protection in a variety of applications, including USB interfaces, portable devices, and hot-swap environments.
