Hot swap controllers are integrated circuits (ICs) that allow a board to be safely inserted and removed while main power is applied. In this type of application, the hot swap controller provides the necessary circuit protection and prevents possible disruptions in the system due to the insertion or removal of the board. The UCC2913DTR is a hot swap controller manufactured by Texas Instruments (TI) that can be used to protect against disruptions due to board insertion or removal. In this article, we will discuss the application field and working principle of the UCC2913DTR.

Application Field

The UCC2913DTR can be used in a variety of different hot swap applications, such as powering large boards in data centers, telecom and networking equipment, computers, and \'cassettes\' for high-volume production lines. The wide range of applications that the UCC2913DTR can be used for makes it ideal for many different hot swap requirements. Additionally, the UCC2913DTR is well-suited for powering systems with high input voltage levels, as it can provide protection against over and under-voltage conditions.

Working Principle

The UCC2913DTR features a variety of features and safeguards to ensure systems are safely powered during hot swap applications. The device is designed to support a wide range of input voltage levels, from 2.8V to 28V. It also incorporates advanced fault protection features such as over-voltage protection, under-voltage protection, over-current protection and short-circuit protection. Additionally, the device features a slew-rate controlled driver to help reduce the inrush current when the device is powered.

The UCC2913DTR is designed to work in conjunction with external power MOSFETs to provide a complete hot swap solution. The controller accurately regulates the power MOSFET\'s gate voltage and provides an output voltage trimming feature to ensure the output voltage is accurately regulated. The device also has an adjustable power-good output that indicates when the output voltage is within the desired range.

In addition to the main hot swap protection features, the UCC2913DTR also includes a range of protection and diagnostic features. It includes an output overload protection feature that quickly shuts down the system in the event of an over-current condition. It also features an over-temperature shutdown feature, which prevents possible damage due to high temperature conditions. Furthermore, the device features an optional diagnostic pin that can be used to monitor the status of the device.

Conclusion

The UCC2913DTR from TI is an ideal hot swap controller for a range of different applications. It features a wide range of protection and diagnostic features, as well as an adjustable power-good output that indicates when the output voltage is within the desired range. With its wide range of application fields and robust operating features, the UCC2913DTR is a great choice for hot swap applications.
