A TPS2456ARHHT is a type of hot-swap controller, a device that enables the hot-swapping of components while communicating with a computer’s motherboard. The TPS2456ARHHT allows the insertion of an element, such as a circuit board, without the need to power off the computer. This is intended to ensure the integrity of the system being added and that the power to any existing components is maintained during the insertion process. Hot-swap controllers like the TPS2456ARHHT are designed for applications where reliable, electrically safe switching is required and prevent incorrect board or component insertion.

The TPS2456ARHHT is a hot-swap controller composed of the controller, power switches and a sense and control circuit. It is commonly used in computer systems that require hot-swapping and those that frequently add and remove components, such as server racks and data centers.

The associated application field for the TPS2456ARHHT is computing and data storage systems, industrial automation, automotive infotainment and other embedded systems. By combining features such as hot insertion, thermal protection, multi-channel control and flexible overcurrent protection, this device provides a comprehensive solution for safely and reliably inserting circuit boards within a computer or connected device.

Working Principle

The TPS2456ARHHT hot-swap controller offers a wide variety of features for safely and reliably hot-swapping circuit boards into a computer system. It uses two power switches and two current sensing resistors to ensure that the circuit board can be safely inserted into a running system without impacting any existing components.

The TPS2456ARHHT is controlled by an external logic signal and offers up to a total of 6A of output current. This controller allows the user to select the ideal overcurrent protection level. The device offers dynamic overcurrent protection, which monitors the actual load current and adjusts the output current limit dynamically.

The TPS2456ARHHT also includes a sense circuitry, which monitors the temperature of the device. This temperature sensing feature enables the hot-swap controller to detect if the device is over-temperature or faulted. The TPS2456ARHHT will then shut down the system as required to provide an appropriate level of protection.

In addition, the TPS2456ARHHT features a fault timer which prevents premature powering off of the device when it has sustained an over-temperature condition. This protects against nuisance trips and transient faults. The timer then locks the system shutdown condition for a predetermined period of time.

The TPS2456ARHHT is an ideal solution for safely and reliably hot-swapping circuit boards into a computer system. Its comprehensive feature set provides a comprehensive solution for controlling the power and temperature of inserted components.
