LTC4251BIS6#TRPBF Application Field and Working Principle

Introduction

The LTC4251BIS6#TRPBF Hot Swap controller is one of the latest products designed by Linear Technology Corp. It is a hot swap control circuit designed to plugging and unplugging boards operating in system environmental power down situations. It monitors the incoming power or battery voltage and provides safe, seamless hot-insertion or removal of circuits while the system is powered up. With its hot swap capability and the ability to support high inrush currents, the LTC4251BIS6#TRPBF Hot Swap controller can provide robust performance in a wide range of configurations.

Description

The LTC4251BIS6#TRPBF Hot Swap controller is a single-channel Hot Swap controller integrated circuit (IC) with over-temperature protection and over-current protection. This Hot Swap controller offers a high level of protection from device damage when a PCBA with a hot-swappable circuit is being inserted or removed from a system. With its ability to handle high inrush currents, it is able to support high information transmission speeds in a wide range of configurations.

Specification

The LTC4251BIS6#TRPBF Hot Swap controller has a maximum power ratings of 2.7A output, 5A maximum load current, a range of -0.3V to +48V, a 6A inrush current and a maximum power dissipation of 1W. It is available in a 6-pin SOT-23 package making it extremely small. It also has an adjustable inrush current limit (I_LIM_SET) to minimize the power-on inrush current. This allows the user to set the level of inrush current to match the system load requirements.

Application

The LTC4251BIS6#TRPBF Hot Swap controller is widely used in systems such as computers, servers, tablets, and mobile devices. It is especially suitable for use when a PCB containing high current devices such as memory modules or interface devices require hot swap protection, or when power is removed from the system suddenly and unexpectedly. With its wide voltage range and over-current protection, it offers reliable performance when hot swapping sensitive devices.

Working Principle

The LTC4251BIS6#TRPBF Hot Swap controller operates by monitoring the input power supply voltage and adjusting its out-put current according to the system requirements. As the voltage rises, the output voltage of the Hot Swap controller adjusts to the desired voltage. When the voltage reaches the maximum rated voltage, the controller will stop the current flow, thus providing over-current protection and preventing damage to the system. In addition, the Hot Swap controller also has an adjustable over-temperature protection to ensure safe operation during hot swapping of sensitive devices.

Conclusion

The LTC4251BIS6#TRPBF Hot Swap controller is an ideal solution for providing safe, seamless hot-insertion and removal of circuits while the system is powered up. It offers a high level of protection against device damage while eliminating the possibility of over-heating or over-currents. With its ability to support high inrush currents, the LTC4251BIS6#TRPBF Hot Swap controller can provide robust performance in a wide range of configurations.
