The STMicroelectronics industrial digital output expansion board based on IPS1025H in a QFN48L package. It provides a powerful and flexible environment for the evaluation of the driving and diagnostic capabilities of the IPS1025HF single high-side, smart power, solid-state relay in a digital output module connected to 2.5 A industrial loads. It can interface with the microcontroller on the STM32 Nucleo via 5 kV optocouplers driven by the GPIO pins and Arduino UNO R3 connectors. Low-power dissipation (RON(MAX) = 25 mΩ)
Propagation delay at startup < 60 μs
Fast decay for inductive loads
Smart driving of capacitive load
Output voltage on/off status feedback
5 kV galvanic isolation
Supply rail reverse polarity protection
