TPS22975EVM is an evaluation board containing the TI TPS22975 Supercapsense power switch. It works as a switch and protection device and facilitates the connection of large portable system designs to one or more batteries, or any other application that requires power and protection. The EVM contains two demo boards, one with a capacitive sensor and one with tactile switch and LED. The EVM can be used to evaluate the performance characteristics of the TPS22975 and assess the application under various loads.

The TPS22975EVM offers an easier and immediate way of evaluating the features of the TPS22975, and allows customers to get more out of the circuit without having to develop it from start. The EVM contains all the necessary components to fully evaluate the device, including the capacitive sensor and/or tactile switch, current and voltage sources, connectors, and a Two-Wire Motor Controller card for closed-loop control using the second demo board.

The main work principle behind the TPS22975EVM is using output voltage feedback to control the output current. This output voltage feedback is enabled when the first demo card with the capacitive touch sensor is connected to the TPS22975 output. If the output voltage drops below the set threshold, the connection is opened and the current is reduced before the circuit can be damaged. The second card with the tactile switch and LED provides output current control, which can be adjusted by the user to best suit their application.

The TPS22975EVM has various applications, ranging from low voltage protection to battery charging and energy storage. It is able to protect a system from overvoltage and overcurrent, resulting in longer system life and improved reliability. Furthermore, it allows users to easily set appropriate thresholds for specific application, such as system power consumption and load current, as well as the maximum allowable output voltage.

In summary, the TPS22975EVM evaluation board contains all of the necessary components to evaluate the TPS22975 Supercapsense power switch. It is ideal for applications that require low voltage protection, battery charging and energy storage. Furthermore, the TPS22975EVM allows users to conveniently adjust the set thresholds to suit their specific application requirements. Finally, the board includes a Two-Wire Motor Controller card for closed-loop current control.
