Evaluation and Demonstration boards and kits are used to test and assess the performance and effectiveness of products and systems. The TPS2552DBVEVM—364 is one such board that provides an in-depth understanding of the features, capabilities, and performance of the TPS2552 active reverse-current protection device. It enables users to view the evaluation results quickly and accurately.

The TPS2552DBVEVM—364 application field includes consumer electronics, automotive, industrial, and medical equipment. This board supports reverse-current protection devices used in USB Type-C applications as well as systems with power supplies up to 20V. Its active reverse-current protection scheme is specially designed to protect downstream device from current overloads or voltage surges.

The TPS2552DBVEVM–364 features a dual-channel active reverse-current protection circuit with current-sensing resistors to provide accurate current limit. It also supports programmable input/output voltage limits with accuracy of +/- 2%. The board utilizes the high-performance microcontroller TPS2552DBV, which is supported by various protections such as overtemperature protection, overvoltage protection, undervoltage protection, as well as electrostatic discharge protection. The device comes with a graphical user interface (GUI) that makes monitoring of current limit and voltage range very easy.

The working principle of the TPS2552DBVEVM–364 is simple. When the input voltage is greater than the current limit, the TPS2552DBV microcontroller opens the N-channel MOSFET, starts current limiting and shuts down the system. The current flowing through the resistor is measured by the microcontroller and used to calculate the current limit. The microcontroller will then adjust the MOSFET gate voltage, keeping the current limit constant. The GUI can be used to adjust the current limit and the output voltage range of the board.

The TPS2552DBVEVM–364 also supports test-mode operation that allows users to determine the accuracy and stability of the system. This mode helps users evaluate the performance of the system under various operating conditions and conditions. The GUI is also used to log any device or system related errors during testing. The board is compatible with LabVIEW, RTOS, and Windows platforms for accurate test and evaluation.

The TPS2552DBVEVM–364 also provides diagnostics and control interface via I2C, GPIB, CAN, and JTAG. The board comes with an onboard power regulation circuit and supports external temperature sensors for temperature-based monitoring of power integrity. It provides real-time data storing and logging of system data, for both real-time and post-mortem analysis.

In conclusion, the TPS2552DBVEVM–364 is a valuable board for testing and evaluation of reverse-current protection devices and systems. With its wide range of features and outputs, it is an ideal tool for testing and evaluation power-related systems. Its onboard diagnostics, control, data logging, and logging functions help users quickly and accurately assess and evaluate the system.
