Evaluation and Demonstration Boards and Kits

The TPS2513EVM-527 is an evaluation module designed to demonstrate the performance of the Texas Instruments TPS2513-Q1 current-limited switch. The module has been designed to provide designers a platform to test and evaluate the device’s operation, relay response time, and adjustability.

Applications

The TPS2513EVM-527 can be used in a variety of applications, such as automotive ignition applications, battery management systems, power supplies, consumer applications, and industrial installations. The board also supports several adjustable parameters, such as current-limit threshold and impedance control.

Working Principle

The TPS2513EVM-527 is a single-chip solution for current-limited switches up to 12.5A. It contains an integrated MOSFET switch with current sensing and a programmable current-limit threshold. The switch’s gate is controlled by an adjustable signal, which can be adjusted by the user. The TPS2513 enables the user to set the current-limit threshold through one of the three available inputs: the high-side current limit, the low-side current limit, or the enable command. The module is protected against overload and over-temperature conditions through integrated current sensing and thermal shutdown features.

The board also includes an adjustable current-limit impedance. This impedance is set by the onboard potentiometer. The response time of the voltage-controlled portion is adjustable using the onboard DIP switch. In addition to the adjustable IVR parameters, the TPS2513 also provides secondary protection functions such as OVP and UVLO.

The TPS2513EVM-527 is a versatile platform for evaluation and demonstration of the performance of the TPS2513-Q1 current-limited switch. Featuring adjustable parameters for turn-on delay, current-limit threshold, and impedance control, the board can be used in a variety of applications.
