TPS259250DRCR

The TPS259250DRCR is a Hot Swap controller from Texas Instruments. Since hot plugging power components can damage connected circuits, Hot Swap controllers are designed to prevent this kind of damage and ensure circuit reliability. The TPS259250DRCR is a 3-A Hot Swap controller that features robust current limiting, dedicated fault management, and multiple circuit protection features.

The TPS259250DRCR Hot Swap controllers are ideal for applications like data centers, network equipment and other systems with multiple hot pluggable components. In these systems, the TPS259250DRCR helps protect against circuit damage due to power cycling, over current, over-voltage and short-circuiting.

The protection features of the TPS259250DRCR are its current limit, inrush control, output voltage slew rate control, over temperature protection, and short circuit protection. It includes a low on-resistance MOSFET switch, as well as an adjustable voltage limit circuit, which helps protect against over-voltage conditions. Additionally, a series resistance is built-in to help manage in-rush current and throttle the startup of a Hot Swap application.

The TPS259250DRCR is designed to fit the current needs of many Hot Swap applications. It can be configured to operate in active current or hot-swap current limiting modes for over-current protection. It also supports low on-resistance MOSFETs, as well as three MOSFETs with a series resistance. All of these features allow it to be optimized to fit various Hot Swap application parameters.

The working principle of the TPS259250DRCR is fairly simple. It monitors an input power rail and monitors the current that is flowing through the MOSFET. If an overvoltage or overcurrent situation is detected, the controller will take action to protect the MOSFET. It will either cut off power to the MOSFET or reduce the voltage to an acceptable level. In addition to these features, the TPS259250DRCR also features over temperature and short circuit protection.

Overall, the TPS259250DRCR from Texas Instruments is an ideal solution for Hot Swap controller applications. Its numerous protection features, adjustable voltage limit, and low on-resistance MOSFET make it an ideal choice for hot plugging systems. Its simple working principle also simplifies the design process and eliminates the need for complex external components.
