The Working Principle of TPS23523EVM-863
The TPS23523EVM-863 Evaluation Board contains two devices that are essential in understanding the working principle of the kit: the TPS23523, and the TPS23530. The TPS23523 is a 3-phase current sense amplifier, and the TPS23530 is a 3-phase high-side current sensing circuit.
The TPS23523 is used to detect the differential current between two points, which is then used to set the output voltage of the TPS23530. The output voltage of the TPS23530 is then used to measure the whole current in the 3-phase circuit. This output is used to drive an indicator LED or some other indicator like a display.The TPS23523 has 16 pins: 8 differential inputs, one ground, 4 supply voltage pins, one gain select pin, one common mode index pin, one output enable pin, and one output pin. The TPS23530 has 8 pins: ground, three supply voltage pins, one gain select pin, one output enable pin, one input pin, and one output pin. The TPS23523 amplifies the differential currents that flow via the two +X and -X lines and one +Y and -Y lines, and generates an output voltage proportional to the magnitude of the differential current. The TPS23530 has an integrated common mode-to-differential voltage (CM2DV) circuit which converts the differential voltage output of the TPS23523 to a linear current through the load.Conclusion
TPS23523EVM-863 evaluation and demonstration boards and kits are developed by Texas Instruments Incorporated (TI). They are used for evaluating, testing, and demonstrating the operation of the TPS23523 3-Phase Open-Drain/Open-Source Current Sense Amplifier. The EVM is a simple and effective platform intended to provide users with an opportunity for quick and easy evaluation and integration of the TPS23523 into a board level design. The TPS23523 is an ideal device for a wide variety of current sense applications such as power delivery systems, medical and industrial systems, robotics, autonomous vehicles, avionics, telecommunications, and industrial power monitoring. The TPS23523 works in conjunction with the TPS23530 which converts the differential voltage output of the TPS23523 to a linear current through the load. The TPS23523EVM-863 provides users with the necessary platform and components to make reliable and accurate current sense measurements.
