LTC4261IGN-2#TRPBF is the integrated hot-swap controller which simplifies the power management design in high power applications. It can be classified under the broad category of PMIC (Power Management Integrated Circuit) application. This product series is capable of controlling the insertion, removal and current flow of DC loads into Live Backplane system/circuit. It provides hot-swap protection during circuit turn-on with support for greater than 38A at 400V DC.

This product has a wide range of application areas like data centre, telecom, telecommunications and networking. As it has a hot-swap controller feature, it can provide best in class power designer for LiveBackplane’s application.Moreover, it is compliant with the PMBus command set to provide comprehensive telemetry and communication interface for monitoring and power control. Not to mention, the low-voltage turn-on feature makes this product an ideal solution for high power and hot-swap applications.

LTC4261IGN-2#TRPBF is implemented with input voltage range of 3V to 56V and a peak current rating of 130A. The current limiting feature of this product makes it ideal for current-limited applications. Apart from that, the thermal protection feature of this product helps in protecting the sensitive circuits even in extreme operating temperature. Additionally, this product has built-in OTP and reverse current protection.

Coming to the working principle of LTC4261IGN-2#TRPBF, the main task is to monitor the insertion and removal of power loads, especially those connected to the DC bus. When the device is plugging into the LiveBackplane, the chip will detect the insertion of the load, turn on the power MOSFET at a safe and low voltage, and then increase it gradually to the desired level. It is done to reduce the inrush current of the load and to prevent damage to the system. Moreover, it also monitors the output current, temperature and any other safety related parameters. If any of these parameters exceed their set limit, the device will automatically turn off the power MOSFET to protect the system. Finally, the device also provides communication interface with PMBus, to enable users to monitor and control the adapter’s current, voltage and temperature.

In conclusion, LTC4261IGN-2#TRPBF is a highly efficient and feature-rich hot-swap controller perfectly suited for high power applications like those in the data centre, telecom, telecommunications and networking. With its current limiting, reverse current protection and PMBus communication interface, LTC4261IGN-2#TRPBF offers an ideal solution for all kinds of hot-swap applications, making it a must-have for power management designers.
