Features• Based on IPS160HF single high-side switch, which features:

– Operation up to 60 V/2.4 A– Low power dissipation (RON(MAX) = 120 mΩ)– Fast decay for inductive loads– Open load detection and diagnostics– Overload and overheating protections with thermal shut-down and cut-off– PowerSSO-12L package

• Application board operating range: 12 to 33 V/0 to 2.4 A• Extended voltage operating range (J1 open) up to 60 V• Status and diagnostic LEDs• 3 kV galvanic isolation• Supply rail reverse polarity protection• Ready for Safety Digital Output Architecture• EMC compliance with IEC61000-4-2, IEC61000-4-3, IEC61000-4-5• Wide application development potential in STM32 Nucleo development

environment• Equipped with Arduino™ UNO R3 connectors• CE certified• RoHS and China RoHS compliant

DescriptionThe X-NUCLEO-OUT08A1 industrial digital output expansion board for STM32Nucleo provides a powerful and flexible evaluation and development environment for2 A (typ.) digital output modules, featuring the safe driving and smart diagnosticcapabilities of the IPS160HF single high-side switch.

The X-NUCLEO-OUT08A1 interfaces with the microcontroller on the STM32 Nucleovia 3 kV optocouplers driven by GPIO pins and Arduino™ UNO R3 (defaultconfiguration) and ST morpho (optional, not mounted) connectors.

The expansion board should be connected to either a NUCLEO-F401RE orNUCLEO-G431RB development board, and can also be stacked with another X-NUCLEO-OUT08A1 or X-NUCLEO-OUT10A1.

Two X-NUCLEO-OUT08A1 expansion boards allows you to evaluate a dual channeldigital output module with 2 A (typ.) capability each, or a 2 A (typ.) single channelsafety digital output module. In the second scenario, the first shield output isconnected to the supply of the second one. Dedicated on-board hardware can beenabled or disabled to activate fast discharge of high capacitive loads, output voltagesensing and additional surge pulse output line protection.
