STMicroelectronics STEVAL-IFP040V1 Expansion Board

STMicroelectronics STEVAL-IFP040V1 Expansion Board is an industrial digital output expansion board based on IPS1025HF in a QFN48L package. The STEVAL-IFP040V1 offers a powerful and flexible environment for the evaluation of the driving and diagnostic capabilities of the IPS1025HF. The IPS1025HF is a single high-side, smart power, solid-state relay in a digital output module connected to 2.5A industrial loads.

The STM STEVAL-IFP040V1 can interface with the microcontroller on the STM32 Nucleo through 5kV optocouplers driven by the GPIO pins and Arduino® UNO R3 connectors. The expansion board allows the connection to either a NUCLEO-F401RE or a NUCLEOG431RB development board. Users can also evaluate a system combining a STEVAL-IFP045V1 stacked on a STEVAL-IFP040V1 expansion board.

Supplying the STEVAL-IFP045V1 via the main supply rail and the STEVALIFP040V1 through the output of the STEVAL-IFP045V1, users can accomplish the typical architecture of a single channel digital output for safety systems. The process stages of the two expansion boards result in a cascaded device. The load connected to the STEVALIFP040V1 production can be delivered only when both cascaded systems work appropriately.
