PMIC, or power management integrated circuits, are essential components in the modern world. The LTC4261IUFD-2#TRPBF is a Hot Swap controller PMIC manufactured by Linear Technology. It is used to maximize the power supplied to, and safely protect, server and storage bays in real-time. The LTC4261IUFD-2#TRPBF was developed with reliable fault protection and power management capabilities offered by Linear Technology, allowing it to be suitable for a range of industrial and commercial applications.

The primary application field of the LTC4261IUFD-2#TRPBF is hot-swap and power entry control for servers and storage bays. As a hot-swap controller, it is designed to slowly ramp up the power draw from system cards when they are inserted, or power-cycled, thus eliminating the voltage droop and ensuring safe and smooth operation of the system. In addition, it can also be used in other applications such as power supplies, power sequencing, and variable power entry distributions.

The LTC4261IUFD-2#TRPBF’s working principle is based on the principle of split-gate MOSFET control which uses two MOSFETs connected in parallel with the load. It works by monitoring the voltage levels at each MOSFET and controlling the gate voltage accordingly. This allows it to control the load current to achieve the desired power level while protecting against overtemperature and overcurrent conditions.

The LTC4261IUFD-2#TRPBF is built with a feature set which provides protection against hot-swap and power-related faults while providing over-current and over-temperature protection. It utilizes the integrated Schottky diode and sense resistor to sense system loading and provide over-current protect and thermal protection using over-temperature sensing and compensation. It features a very low delay time of 2µs with a maximum duty cycle of 100%.

To meet the various protection requirements, the LTC4261IUFD-2#TRPBF comes with an adjustable maximum current limit, undervoltage lockout protection, adjustable input voltage range, and adjustable operating temperature range. It also has a wide operating temperature range of -40°C to +125°C and comes in a thermally-enhanced 5-lead SOT-23-5 package.

The LTC4261IUFD-2#TRPBF is a highly efficient and reliable Hot Swap controller PMIC developed with the latest technology, making it ideal for a wide range of industrial and commercial applications. With its low voltage droop capability and intelligent fault-protection, the LTC4261IUFD-2#TRPBF provides the highest level of protection and power-regulation for server and storage bays.
