With the development of technology and the wide application of the electronics industry, power management plays a very important role in the entire production process. The TPS24720RGTT hot swap controller is one of the crucial components to provide important power management capabilities. This article describes its application field and working principle.

Introduction

The TPS24720RGTT hot swap controller adopts a high efficiency hysteretic control method, which is specially designed for the load port insertion demands of quickly hot swap products with high precision current limiting and overload protection, and it can play a great role in the low power protection of devices. It has the advantages of protection against shorts and reversals, adjustable impedance and fast response. The controller limits the output current and provides an accurate current limitation compared to other solutions. It can also provide visual indicators to rescue the system when certain errors occur.

Application Field

The applications of TPS24720RGTT hot swap controller include low voltage applications in data centers, Industrial PCs, communications, medical and enterprise systems. Relevant operators can choose different hot-swap control methods according to their own product needs. With the application of this hot swap controller, the operator can easily upgrade their server products with hot-swap functionality based on I2C standard and others. The TPS24720RGTT hot swap controller can also provide quick insertion and removal of the load device, which can protect the system from over-voltage, over-current and short-circuit failures.

Working Principle

The TPS24720RGTT hot swap controller integrates a fixed current limit stage, an adjustable current limit stage and an adjustable voltage limit stage. When the IN and OUT pins are short-circuited, the controller will immediately turn off the control signal output. It also integrates a wide-input-range buck switching regulator with a pseudo-fault protection function, and provides a voltage tracking shutdown protection feature. When the voltage is above the predetermined value, the controller will send the shutdown signal. The controller will actively monitor the power switch to ensure that it works in the correct range.

When the current reaches the predetermined value, the controller will switch off the power switch in order to reduce the risk of current overload. The source voltage must be higher than the load voltage and the load power must be smaller than the source power. The controller varies the gate voltage of the power switch according to the voltage difference between the two. When the current is greater than the maximum current, the controller will take immediate action to limit the over current, pushing the load device into a safe operating state.

Conclusion

In conclusion, the TPS24720RGTT hot swap controller provides accurate current limiting, overload protection and voltage tracking shutdown protection, and can be used in a wide range of applications. With its hot-swap control technology and innovative design, it can provide reliable power management for many products.
