The STEVAL-IFP028V1 evaluation board enables the IPS160H single high-side switch to be analyzed for systems compliant to SIL2 and SIL3.
The board meets application requirements for galvanic isolation between the user interface and the power interface through optical isolation implemented with two optocouplers, OPTO1 and OPT2, for forward signals to the device and for diagnostic feedback signals, respectively, in compliance with IEC 61000-4-2, IEC61000-4-4, IEC 61000-4-5 requirements.
The STEVAL-IFP028V1 can operate in the 8V to 60V range, but operation of the red LED on the DIAG pin is only ensured above 12V Vcc. Jumper J1 must be open for supply voltages above 40V to avoid permanent damage to the SMCJ40CA transient-voltage-suppression (TVS) diode.
The board optimizes thermal performance through a careful layout which includes a dedicated copper area connected to the exposed pad of the PSSO12 package, which also serves to dissipate heat.
Using your PC, you can monitor the status of the output on the power side and receive fault information from the IPS160H DIAG pin by connecting the STEVAL-PCC009V2 interface board between your PC via USB, and the STEVAL-IFP028V1 board via a 30-way flat cable. The STSW-IPS16X GUI software, is offered for free download.
