PMIC - Hot Swap Controllers are broadly defined as components which enable the control of a power path, allowing a powered device to be safely powered up or down and, most importantly, hot-swapped.

TPS25940LRVCT is a Hot Swap Controller from Texas Instruments. It is used in computing and telecom applications to offer device and system level protection from damage and disruption due to short-circuit events. The device offers variable current limit settings which provide the system designer with flexibility to design the power path to account for linear and switch mode components.

The device has two main applications: protection and control. The protection application has two main functions. Firstly, it provides system-level protection against over-current and inrush conditions. Secondly, it protects the downstream components from damage from transient conditions. In the control application, the device has a number of features to manage the power path. This includes over-current protection, thermal warning and limiting, fault reporting and restart, and adjustable slew rate control.

The TPS25940LRVCT\'s working principle is based on an on-off control method that is capable of detecting an over-current or fault condition. When a fault condition occurs, the device turns off the power path. When the fault is removed, the device will automatically detect this and turn the power path back on. This simple solution reduces system stress and provides power sequencing to ensure a safe power up and power down sequence.

In addition tosystem protection and control, the TPS25940LRVCT also offers robust fault reporting and protection mechanisms. These include input over-voltage protection, device over-temperature protection, and short-circuit protection. These features provide a safe and reliable solution for system protection in the event of a short-circuit event.

The TPS25940LRVCT is designed to be used in a wide range of computing and telecom applications due to its robust protection and control features. This device is a perfect solution for systems that require a reliable and safe system power form factor. The device has adjustable current limit settings and built-in protections making it a first choice for system designers that require a safe and reliable system power form factor.
