The MIC2085-MBQS-TR is a Hot Swap controller designed for managing safe insertion and removal of power supplies from a live load. It has many applications in electronics engineering, requiring it to constantly switch devices and loads in and out, controlling the input and output of hot-plug devices like servers, storage units and other IT equipment. Moreover, it can be used as a main power switch in various applications, where a reliable and robust solution is needed to monitor and regulate the high current. As a Hot Swap Controller, the MIC2085-MBQS-TR provides plug-and-play functionality to protect any power load from voltage overshoots and transients.

The MIC2085-MBQS-TR is designed for high performance and ease-of-use in modern electronic circuits. The device features a low standby current of less than 2µA and quiescent current switching of less than 4mA, allowing for a wide range of applications. It also features an adjustable current limit range from 0.25A to 10A, adjustable in 1mA increments, as well as a high-frequency pulse-width modulation (PWM) at 1/2/3.3V. The MIC2085-MBQS-TR also features an adjustable maximum duty cycle of up to 95%, ensuring a highly regulated and stable output.

The main benefit of the MIC2085-MBQS-TR is its ability to provide a robust solution for safely transferring a high current load from one power source to the other. It offers an adjustable current limit and over-current protection that helps protect any power load during a hot-swap operation. When using the device for load switching, the MIC2085-MBQS-TR will shut down the device in case of any detected over-current. Additionally, it also offers over-voltage protection with user-adjustable thresholds and is able to provide a constant output voltage, limiting the risk of damaging any attached equipment.

The MIC2085-MBQS-TR employs open-drain outputs, which are ideal to use for power load switching in general applications. Open-drain outputs are designed to draw minimal current, allowing for safety and reliability. Additionally, the MIC2085-MBQS-TR also offers short-circuit protection that is able to detect any short-circuits during operation and shut down the device accordingly. Further, it includes an auto-discharge function that automatically discharges the output voltage after the power has been turned off, protecting the equipment from any risks of over-voltage.

Moreover, the MIC2085-MBQS-TR also offers a wide range of other features, such as an adjustable soft-start to reduce inrush current, a hysteretic current limit to reduce excursions during high-inrush current applications, an adjustable dead-time to reduce power dissipation, as well as an adjustable timing to boost power surge mitigation. Additionally, the device also offers protection against over-temperature, reverse polarity, false pull-down or incomplete power-on sequences, as well as an adjustable UVLO detection.

In conclusion, the MIC2085-MBQS-TR is an ideal Hot Swap controller for modern electronic circuits, offering a range of features that ensure reliability and robustness. It has a wide range of applications, from power load switching to other current limit applications, all of which benefit from the device’s adjustable parameters, high level of protection and easy-to-use operational design.
