TPS24701DGK Hot Swap Controllers Application Field and Working Principle

TPS24701DGK Hot Swap Controllers are applicable in a variety of fields and specialize in dealing with current surges and/or power cycles. This type of controller is usually used in server applications such as daisy-chaining and hot-swapping of loads or peripherals, or where large currents or larger than expected power are drawn and where there is a need for current limiting, regulating, monitoring and/or protection.

The TPS24701DGK Hot Swap Controllers feature a maximum I_LIMIT capability of 8A and dual chip enable (CE1 and CE2) logic due to having two enable pins. Additionally, the current measurement pin (CS) serves as the current monitoring pin for use in over-current protection for when I_LIMIT is exceeded. This feature makes the TPS24701DGK Hot Swap Controllers suitable for a variety of applications in which current protection is a priority.

The TPS24701DGK Hot Swap Controllers include several safety features. Automatic FET control (AFC) changes the gate turn-on and turn-off thresholds in response to over-current or over-temperature events to help protect the device during high-current or thermal events. Additionally, the AFC has adjustable gate turn-on and turn-off thresholds that can be programmed with internal or external resistors to provide an extra layer of protection.

Another safety feature included in the TPS24701DGK Hot Swap Controllers is the adjustable overtemperature-warning (OTW) function. This function is triggered when the integrated thermal diode temperature rises above the set threshold. This can be used to limit device power dissipation in cases where the device exceeds its maximum allowable power dissipation.

The TPS24701DGK Hot Swap Controllers feature built-in current monitoring and protection including adjustable current-limit and adjustable overtemperature warning thresholds. In addition to this, the controller features dual chip enable (CE1 and CE2) logic to provide additional system protection in the event that I_LIMIT is exceeded.

The TPS24701DGK Hot Swap Controllers are designed to provide reliable and reliable current-limit protection, while minimizing system-level power dissipation. The devices are available in various packages and wide operating temperature ranges.

In conclusion, the TPS24701DGK Hot Swap Controllers provide a range of safety, protection, and current-limit features suitable for a variety of applications. The controller’s adjustable current limit, dual chip enables, and overtemperature warning functions allow for the efficient and safe removal or insertion of loads or peripherals. Thanks to their features and current monitoring pin (CS), these controllers help to limit system-level power dissipation, providing an efficient current limiting and regulating solution.
