The TPS2491DGSRG4 is a hot swap controller and power path supervisor. Hot swap controllers are power management integrated circuits which are used to safely supply power to electronic components that may be added or removed while the system is running. They provide protection against overvoltage, short-circuits and overcurrent. The TPS2491DGSRG4 has an integrated 5-bit power path supervisor to monitor the supply voltage and current. Its operating voltage range is 2.5V to 5.5V and it is rated for a power supply current up to 4A.

The TPS2491DGSRG4 can be used in several applications, including computers, servers, routers and switches, where power and board space are limited. It is used in systems where a hot swap feature is needed to meet safety standards, such as in servers where a CPU is added or removed during operation. The TPS2491DGSRG4 allows the system to safely power on the added component without requiring a controlled power-on sequence or a manual reset.

The hot swap controller consists of several different blocks, each performing a specific function. The control block provides logic control for the hot swap controller. It takes in digital inputs and provides a digital output. The power path supervision block monitors the supply voltage and current to detect overvoltage, short circuit current and overcurrent conditions. The protection block provides protection against overvoltage and overcurrent conditions. The output control block provides the necessary control signals to the power path supervisor and protection blocks.

The TPS2491DGSRG4 is a versatile device with several features. It has a built-in overvoltage and overcurrent protection to prevent damage to the component being hot swapped. It has an adjustable triggering threshold which allows the user to set the desired overvoltage and overcurrent limits. It also has a built-in inactive gate drive which allows the device to remain in a safe non-on state when the system is not in use. It also has a 5-bit power path supervisor which monitors the supply voltage and current to ensure the hot swapped component is receiving the correct power.

The TPS2491DGSRG4 is a reliable and cost-effective solution to provide hot swap protection in electronic systems. It has a variety of integrated features to ensure the system remains safe and reliable even when hot swapping components. Its adjustable overvoltage and overcurrent protection, built-in inactive gate drive, and 5-bit power path supervisor make the TPS2491DGSRG4 an ideal choice for a wide range of applications.
