STMicroelectronics IPS161H | Demoboard STEVAL-IFP034V1

Description

The STEVAL-IFP034V1 evaluation board is designed to analyze the IPS161H device functionality. It provides galvanic isolation between the user interface and the power interface through optical isolation implemented with optocouplers OPTO1 for forward signals to the device and OPT2 for diagnostic feedback signals. IEC 61000-4-2, IEC61000-4-4 and IEC 61000-4-5 compliance is achieved by the IPS161H itself and the U1 component (the external TVS between VCC supply rail and power ground). A dedicated GUI interface helps you test IPS161H functionality. To use it, ensure the STEVAL-IFP034V1 is connected via a 30-way flat cable to a STEVAL-PCC009V2, which is connected via USB to the PC running the GUI. The GUI allows driving the STEVAL-IFP034V1 and monitoring the power output status with fault information from the IPS161H DIAG pin. The STEVAL-IFP034V1 also optimizes thermal performance, thanks to a dedicated copper area which connects the PSSO12 package exposed pad and acts as a heat sink.
