Power management integrated circuits (PMICs) are widely used for regulating and controlling the electric power within various electronic devices. Within the PMICs, hot swap controllers are particularly useful to manage instant, momentary, and/or quick power changeovers. The Texas Instruments TPS2390DGKR is an active power-management hot swap controller IC specifically designed to support the safe insertion, removal, and controlled shutdown of servers, networking equipment, and other IT data equipment.

The TPS2390DGKR is a feature-rich device that provides myriad safety features, including: overvoltage protection, undervoltage protection, hot insertion protection, overcurrent protection, start up in-rush protection, fault protection, and overtemperature protection. It increases system reliability by enabling hot-plug insertion of components into even low-capacity circuits. It also features a fault-type output and latching-controlled turn-on/turn-off, which help increase system reliability during and after hot insertion.

Typical applications for the TPS2390DGKR includes use in many popular server platforms for powering PCIe and "low-end" SAS busses. It could also be used in rack/tower server plans, computing complexes, as well as high-end workstations. The IC supports two redundant power-management paths for hot-swap applications.

At the core of the TPS2390DGKR is its dual bidirectional main switches that provide efficient power control. Its integrated fault management allows onboard device diagnostics on both the power supply inputs, as well as the outputs. The IC also features a programmable soft-start generator, which is designed to support the rapid power-up of power-supply-undervoltage systems. Additionally, the device features current sensing and internal diagnostics with a pre-defined threshold.

The TPS2390DGKR is a component that allows engineers to quickly and easy incorporate hot swap control into their electronic design. It helps ensure that power supplies are properly connected and uncoupled from the system with minimal peripheral components. The component also ensures that the system maintains adequate power without damaging the connected devices during power operations.

With its highly integrated design, the TPS2390DGKR can guarantee system reliability and power management performance by using the two independent paths for transferring power. As such, the component provides improved safety for hot-swap operations. It also includes extensive safety protections, current and voltage monitoring, fault detection, thermal overload protection, and low-on-resistance drivers that offer efficient power switching at a low level of power consumption.

In summary, the Texas Instruments TPS2390DGKR is an advanced hot swap controller IC designed to deliver safe power supply insertion, removal, and controlled shutdown of servers and other data equipment. It features a host of integrated safety and power-management features and integrated fault management, which help ensure the safe execution of hot-swapping operations. Its feature-rich design makes it a valuable component for engineers who are looking for an efficient way to incorporate hot swap control into their designs.
