The TI TPS2390DGKG4 is an intelligent, easily programmable hot swap controller integrated circuit (IC). It is designed to be used in power supply design, power distribution, electrical engineering, and other applications where a reliable hot swap controller can be used. The TPS2390DGKG4 is available in an 8-pin SOIC (small outline integrated circuit) and a VQFN (very small package).

The TPS2390DGKG4 is a programmable hot swap controller that can be applied in any typical power distribution system that requires hot swap hardware. It has a tungsten oxide voltage and current sense with a threshold voltage of 2.45V and an overvoltage protection of 10V. With its programmable output current threshold, the device allows for detection of overcurrent events, and can support up to 0.5A.

In addition, the TPS2390DGKG4 provides a wide range of programmable features such as hot swap enable, power up and down delay, soft-start ramp, and over voltage protection. It also supports a wide range of enable inputs, including manual enable, enable over current, and enable on power up.

At the heart of the TPS2390DGKG4 is its digitally-controlled, Auto-Retry™, Fault Retry and Programmable Over Current Protection (OVP) sub-systems. At the time of a fault event, the Auto-Retry™ feature protects downstream components from over-stressing by limiting the number of retry attempts. If the fault persists, the Fault Retry will automatically disconnect the load. The OVP helps prevent damage to the system by limiting inrush current during load startup and limiting maximum current through the load.

The TPS2390DGKG4 provides additional system protection through its adjustable dead-time protection. This feature prevents the system from being damaged when attempting to transfer a load between multiple power sources. The adjustable UVLO feature helps protect the system against voltage spikes. Additionally, the device boasts a Smart Diode feature that reduces charge ripple, improving the efficiency of the power system design.

With its integrated hot swap controller and slew rate limit control, the TPS2390DGKG4 is designed to simplify the development time of a power solution. The ease of programming and the ability to adjust the voltage and current parameters ensures the system design can be customized for optimal protection and performance.

In summary, the TPS2390DGKG4 is an ideal power supply design and power distribution solution for applications requiring high levels of protection, efficiency, and reliability. Its adjustable voltage and current parameters make it easy to customize the system design for optimal protection, while its Safety Shut Down feature helps prevent damage resulting from over voltage and over current events. With its intuitive programming interface, the TPS2390DGKG4 makes it easy to integrate hot swap controllers into a power solution.
