Texas Instruments TPS2492PWR- Hot Swap Controllers

A hot swap controller is an electronic circuit that allows for the insertion or removal of a circuit board or other component from a running system without causing damage to the system or disrupting its operation. This type of controller provides protection against power surges, voltage spikes, and current surges that can occur during the hot-swapping process.

 

The hot swap controller is typically placed between the power supply and the device being inserted or removed, and it monitors the voltage and current going into and out of the system. If it detects any abnormality, such as a sudden surge in current or voltage, it will shut off the power before the problem can damage the system. Some hot swap controllers also provide advanced features such as current limiting, soft-start, fault detection, and thermal shutdown to further protect the system and improve performance.

TPS2492PWR Description

The TPS2492PWR is easy-to-use, positive high voltage, 14-pin Hot Swap Controllers that safely drive an external N-channel FET to control load current. The programmable power foldback protection ensures that the external FET operates inside its safe operating area (SOA) during overload conditions by controlling of power dissipation. The programmable current limit and fault timer ensure the supply, external FET, and load are not harmed by overcurrent. Features include inrush current limiting, controlled load turn-on, interfacing to down-stream DC-to-DC converters, and power feed protection.

 

The analog current monitor output provides a signal ready for sampling with an external A/D converter.

Typical Application Circuit

Principle

The TPS2492PWR works by monitoring the voltage and current flowing through a load and controlling the MOSFET switch that is placed in series with the load. When a fault condition occurs, such as an overcurrent or overvoltage situation, the TPS2492PWR will shut off the MOSFET switch to protect the load from damage.
