The TPS2320IDRG4 is an integrated hot-swap controller with a low-inrush current regulating feature that helps protect the host system. It is a device for driving high-current applications such as server farms and heavy loads. The device offers a system-level control point with precise edge rate control and precise overload current control. It is a great choice for high-current host application designs.

Overview of TPS2320IDRG4

The TPS2320IDRG4 is an integrated hot-swap controller that helps protect host systems from high inrush currents. It features low inrush current regulation and a high-current turning on capability. This device uses two high-current channels and a microcontroller-based control system to provide precise edge rate control and precise overload current control. It also offers robust protection circuits suitable for protecting the load during hot-swap conditions. The device operates with a wide input voltage range, up to 15V, and is capable of driving loads up to 95A. It also provides a Reset signal indicating the active load current.

Application Areas of TPS2320IDRG4

The TPS2320IDRG4 is suitable for high-current applications such as server farms, communications systems and other high-load designs. It is ideally suited for hot-swap applications, allowing the load to be powered safely and quickly during plug-in and unplugging operations. It is also suitable for high-current transient applications such as remote power-up or down operations. It can eliminate inrush current during the power-up sequence and help prevent load or system damage.

Working Principle of TPS2320IDRG4

The TPS2320IDRG4 functions by using two high-current channels, one for the load and the other for the host. When the system power is applied, the load channel turns on and supplies power to the load. The host channel then monitors the load current and adjusts the edge rate to limit the inrush current. When the load reaches its maximum current capacity, the host channel will automatically turn off the load channel. The Reset signal is then used to indicate the active load current, allowing for accurate and precise control.

The TPS2320IDRG4 hot-swap controller also features an overload current protection circuit. This circuit features an adjustable current value that monitors and restricts the amount of current available to the load. If the load exceeds the maximum current setting, the circuit will immediately turn off the load channel, thus protecting the load and system components from damage. The circuit will then reset and allow the load to power up again.

Conclusion

The TPS2320IDRG4 is an ideal choice for high-current applications. It is a versatile device that offers precise edge rate control and overload current protection, as well as a reset signal indicating the active load current. It is a great choice for hot-swap applications and offers robust protection for the load and system components. With its wide input voltage range and powerful output current, the TPS2320IDRG4 is a great choice for host application designs.
