The TPS2459RHBR is a hot swap controller that allows the insertion and removal of components into a live backplane. The device is designed with a low-power power switch circuit to protect the system in the event of an over-current and overtemperature fault. The device is operational over a wide input voltage range, up to 5.5V, and is suitable for systems requiring hot-swap capability. The device allows for hot insertion and removal of components, providing system protection for over-current, overtemperature and overvoltage fault conditions, and is ideal for use in remote systems, hot plug and play applications, and redundant power systems.
The TPS2459RHBR hot swap controller provides protection from overcurrent faults within an operating system. The controller is designed to limit the amount of current that is sourced or sunk by the system by quickly disconnecting the component in the event of an overcurrent. Once the fault condition has been cleared, the device resets and reconnects the component allowing the system to function normally.
The TPS2459RHBR also provides protection from overtemperature faults, which can occur due to component failure or environmental conditions. The device monitors the junction temperature of the component and disconnects the device upon reaching the overtemperature threshold. This prevents further heat build-up and minimizes any potential damages to the component.
The TPS2459RHBR hot swap controller can provide protection from overvoltage faults. The device uses an analog circuit to monitor the input voltage and disconnect the component if the voltage reaches the overvoltage limit. This prevents the component from being exposed to the greater voltages and consequential damage.
The TPS2459RHBR allows for efficient power control, as the device can be used to control the power-up and power-down sequence of the component. The device is capable of source sequencing, wherein the component is powered-up before the backplane, and sink sequencing wherein the component is powered-down before the backplane. This provides protection to both the component and the system by providing efficient power control.
The TPS2459RHBR hot swap controller also provides protection from short circuit faults during insertion and removal of components. The device is designed with a short circuit protection circuit which opens the switch circuit in the event of a short circuit condition. This helps protect the component and the system from any potential damage.
In summary, the TPS2459RHBR hot swap controller is an ideal choice for a variety of applications requiring hot-swap capability. It provides comprehensive protection from over-current, over temperature and overvoltage fault conditions as well as protection from short circuit faults. The device also provides efficient power control and allows for the easy insertion and removal of components in a live backplane.
