The TPS2399DGKG4 is a hot swap controller designed to maximize circuit flexibility and reliability when powering multiple devices connected to a single power rail. The device is ideal for applications where PMIC-controlled, hot-swap boards are used. It is designed to operate at currents as low as 0.3A and up to 100A. The TPS2399DGKG4 combines the functions of a power control and switching device, resulting in a more reliable and flexible power system.

The TPS2399DGKG4 is a Hot Swap Controller, so the device is suitable for applications where a secure supply of power is essential. The device provides an IO-level control interface for controlling the power supply between an input logic supply and an output power supply. This allows the user to control power supply up to 30V in an output load with up to 100A. The controller also provides an adjustable over-current protection voltage and over-voltage protection voltage, allowing the user to control the power supply outside the allowed operating range. Furthermore, the device can also provide a status pin that indicates the power state, allowing the user to monitor the condition of the power supply.

The device has a selectable input logic control for the power switch with supply logic voltage up to 7.5V. It also has a selectable power switch, with an adjustable voltage from 2.3V to 30V. The power switch features a high current level and its own integrated MOSFETs to enable a fast ON/OFF operation. The device also has a shutdown pin that allows the user to temporarily disable the IC.

The TPS2399DGKG4 also includes a host controller interface for communication with an external microcontroller. The device can be programmed to integrate with control systems such as USB, UART, and I2C. The device also includes a connected supply pin that allows the user to monitor the input and output voltages of the power supply. This pin provides a way to detect when the power supply is delivering the correct voltage.

The TPS2399DGKG4 also has a thermal and reverse current protection. The thermal protection feature allows the device to sense temperature changes and adjusts the input voltage and current accordingly. The reverse current protection feature prevents the device from drawing more current than the maximum current specified in the datasheet. This feature protects other components from damage from overloading.

The TPS2399DGKG4 is a fully integrated hot swap controller for applications such as digital electronics and industrial applications. It is available in a variety of packages including a 5x5mm QFN and a 5x5mm QFF package. The device is suitable for use in a wide variety of applications where reliable and secure power supply is essential.
