STEVAL-IFP034V1

STEVAL-IFP034V1 Data brief Single high-side driver based on IPS161H Features • • • • • • Operating voltage range: 8 to 60 V Operating current: 0.5 A max Programmable cut-off delay time Reverse polarity protection Galvanic isolation on PCB Input pins compatible with VCC rails • • Green LED for channel ON/OFF status Red LED for Common Diagnostics on: – open load in OFF state – cut-off – thermal protection Microcontroller interface Compliant with IEC 61000-4-2, IEC61000-4-4 and IEC 61000-4-5 RoHS compliant • • • Description The STEVAL-IFP034V1 evaluation board is designed to analyze the IPS161H device functionality. Product summary Single high side driver based on IPS161H STEVALIFP034V1 Single high-side switch for safety integrity level (SIL2 IPS161H and SIL3) compliant systems 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.
