Evaluation and Demonstration Boards and Kits are a device that contains a circuit designed to allow engineers and technicians to evaluate and demonstrate a product or a specific circuit. The TPS2390EVM is a device that offers evaluation and demonstration for Texas Instruments\' TPS2390 Hot Swap controller . This device allows a user to easily evaluate the full range of features of the TPS2390, such as current limiting, voltage monitoring, and fault protection for load circuits connected to a VCC rail. Additionally, the device also has an on-board load circuit with an LED indicator to allow users to quickly and easily evaluate the load current thresholds and fault protection.

The TPS2390EVM application field is most commonly found in industrial automation, networking, and consumer electronics. Its main function is to provide fault protection and current limiting for devices connected to VCC rails that require hot-swap capabilities. In industrial automation, it can be used to protect a device from over current, over voltage, and short circuit when it is connected/reconnected to a power rail. In networking applications, the device can be used to provide power to edge devices such as sensors, and it can provide current limiting and fault protection for those connected devices. In consumer electronics, it can be used in a variety of applications, such as providing power to a mobile device or a tablet computer.

The working principle of the TPS2390EVM relies on the controller\'s integrated hot-swap circuitry, which consists of a MOSFET power switch and other internal circuits. The MOSFET power switch is used to control the power supply to the load, and the internal circuits monitor the rail voltage and the current. When the VCC rail voltage drops, the controller will reduce the duty cycle of the power MOSFET to adjust the current until the required voltage is restored. If an over-current is detected, the controller will reduce the duty cycle to limit the current. Additionally, the device is equipped with a load LED indicator, which can be used to visually verify that the current is reaching its required value.

The load circuit on the TPS2390EVM can be adjusted with a potentiometer, allowing the user to select different load current thresholds and fault protection thresholds. Additionally, the user can adjust the device to provide current limiting and fault protection for a variety of different load circuits. This enables the user to evaluate the performance of the hot-swap controller with a variety of different load conditions.

In conclusion, the TPS2390EVM is a device that offers evaluation and demonstration for Texas Instruments\' TPS2390 Hot Swap controller. It provides current limiting, voltage monitoring, and fault protection for load circuits connected to a VCC rail. Its application is most commonly found in industrial automation, networking, and consumer electronics. It works by controlling a MOSFET power switch and monitoring the rail voltage and current, and the load circuit can be adjusted by a potentiometer so that users can evaluate the device with different load conditions.
