PMIC, or Power Management Integrated Circuit, is a component that helps manage and control electrical signals in electronics. As the name suggests, it is an integrated solution for providing electricity to electronic circuits. One component of the PMIC family is the hot swap controller, which is designed to provide high quality and ongoing protection for electronic systems. The TPS2393APWG4 is an advanced hot swap controller that can offer reliable power delivery and protection in challenging environments.

Overview

The TPS2393APWG4 is a hot swap controller that uses the advanced PGOOD (Power Good) signal feature. This signal reduces design complexity and increases overall system reliability by providing feed-forward and feedback information to the hot swap controller. In addition, the device features an UltraFast™ turn-on time of 26ns. This helps ensure safe and reliable system power up even in systems that require quick, dynamic load transient response.

Application Field

The TPS2393APWG4 is designed for use in a variety of applications that require hot swap control and high-level ESD protection for system components. It is ideal for systems operating in challenging environments, including automotive, railway, industrial, audio, and medical applications. Additionally, it is suitable for use in telecommunications and networking applications such as switches, routers, base stations, and Wi-Fi access points. It also provides a cost-efficient solution for hot plugging and high-speed data transfers.

Working Principle

The TPS2393APWG4 hot swap controller is based on a hybrid circuit structure that operates using both linear and digital control. The device utilizes three key timing signals: EENX, PGOOD, and ALERT. EENX is an enable signal that is used to activate/deactivate the device and control when it is turned on and off. PGOOD is a signal that is generated when the output voltage is stable and within tolerance. Finally, ALERT is an output signal that indicates whether PGOOD is asserted or an undervoltage (UV) or overvoltage (OV) situation has occurred. The circuit also includes overcurrent protection (OCP) to prevent the load from exceeding the maximum current.

The TPS2393APWG4 monitors the voltage from the load and ensures that it is within a predetermined range. If the voltage exceeds the specified level, the device will shut down the system and turn off the supply. It also monitors the current and will limit it to the maximum current rating if the load exceeds the designed threshold. Finally, it provides ESD protection for the load and ensures that the system is protected against devices subject to electrostatic discharge.

Conclusion

The TPS2393APWG4 hot swap controller is a powerful and reliable device that provides reliable power delivery and protection in challenging environments. It is suitable for a variety of applications, including automotive, industrial, audio, telecommunications, and networking. Additionally, it features an UltraFast™ turn-on time and provides overcurrent protection and ESD protection for the load. Overall, the TPS2393APWG4 is an ideal solution for hot plugging and high-speed data transfers.
