Product summary Single high side driver based on IPS160H STEVALIFP028V1 Single high-side switch for safety integrity level (SIL2 and SIL3) compliant systems IPS160H STM32-based USB-toserial interface bridge board STEVALPCC009V2 GUI for STEVALIFP028V1 and STEVALIFP034V1 STSW-IPS16X 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 8 to 60 V range, but operation of the red LED on the DIAG pin is only ensured above VCC = 12 V, and you must ensure that jumper J1 is open for supply voltages above 40 V to avoid permanent damage to the SMCJ40CA transient-voltage-suppression (TVS) diode. The board also 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. You can use your PC to monitor the status of the output on the power side and receive fault information from the IPS160H DIAG pin by connecting the STEVALPCC009V2 interface board between your PC (via USB) and the STEVAL-IFP028V1 board (via 30-way flat cable), and then running the STSW-IPS16X GUI software, which is freely available on the ST website.
