Power Management Integrated Circuits (PMICs) are components in a wide range of electronic devices, from consumer products to machines, that manage and regulate the power delivered to them. PMIC Hot Swap Controllers are specialized to manage high voltage, high power applications. Such is the case for the MIC2596-1BTS Hot Swap Controller.

The MIC2596-1BTS, or the Hot Swap Controller, is an integrated circuit that serves to manage, protect and regulate from high voltage and high power sources, maintaining the current and voltage flow to and from the supplies within safe operating levels. It has two independent outputs and two distributed switches that respond to and address an external remote sense and overvoltage/ undervoltage/power-good (OV/UV/PG) detection feature.

When used as a Hot Swap Controller, it then provides complete electrical isolation, which is highly important and deemed necessary to prevent the occurrence of damage, be it the power supply, load, or the entire circuit itself. This means that while in operation and while current and voltage is definitely flowing, there is no way to establish a direct physical connection between the power source and the load.

Components included in the MIC2596-1BTS Hot Swap Controller include two HP power MOSFETs, an error amplifier, an over-temperature protection circuitry and a supply rail monitor. It also features a shut-down delay of up to 19 seconds before turning off to indicate that the INT_PG threshold has been exceeded, a feature which serves to protect the device in the event of an overvoltage situation.

The unique design of the MIC2596-1BTS utilizes a series of Analog and Power Management processes to increase efficiency and reduce the generation of unwanted heat. Its integrated error amplifier serves to detect a drop in voltage on the output, thus allowing the device to automatically adjust the output to bring it back to the set safe operating level, combined with its programmable fault tolerance to prevent tripping of power.

The integrated power MOSFETs serve the purpose of chopping current peaks and offering a higher resistance to distinguish between a low-side and high-side fault. It also enables faster control loop transient response and a quick response to changes in the temperature of the MOSFETs itself. This further improves the system’s overall performance and allows for a much more accurate current limiting response as well.

The MIC2596-1BTS provides much more than just a Hot Swap Controller. It has an array of configurations which can be employed to provide protection against a wide range of internal and external faults and events, such as undervoltage lockout, current limit threshold, overvoltage protection and thermal shutdown protection.

All these features are what make the MIC2596-1BTS the perfect choice for any high voltage and high power application requiring efficient and reliable management of current and voltage flow. Not only does it provide complete electrical isolation to ensure safety, but also allows flexibility in its options to suit any application.
