Overview

The X-NUCLEO-OUT12A1
20 MHz SPI and Power Good diagnostic, overcurrent and overtemperature protection for safe output loads
control.
The board is designed to meet the application requirements for the galvanic isolation between the user and power
interfaces.
The galvanic isolation embedded by the
optocouplers, with a consequent cost saving and a reduced application size.
The expansion board features:
• Based on the
– Operating range 9.2 to 36 V
– Low power dissipation (R
– Process side operating current: up to 0.7 A per channel
– Embedded 2k V
– PGOOD (VCC voltage level alarm signalization)
– 20 MHz SPI with daisy chaining
– Fast decay for inductive loads
– Undervoltage lock-out
– Overload and overtemperature protections
– Loss of ground protection
– PowerSO36 package
• Application board process side operating range: 10 (J10 open) to 33 V (J9 closed)
• Extended operating range of process side from 9.2 (J10 closed) up to 36 V (J9 open)
• Application board logic side operating voltage 3.3 to 5 V
• Green LEDs for outputs on/off status (J6 and J7 close 1-2, 3-4, 5-6, 7-8)
• Red LED for common overheating and communication error diagnostic (J3 close 1-2)
• Red LED for PGOOD signalization (J3 close 3-4)
• Yellow LED for output enable status signalization (J3 close 5-6)
• Process and logic supply rails reverse polarity protections
• Compatible with
• Equipped with Arduino
• RoHS and China RoHS compliant
• CE certified
• Radiated emission: class B according to the standard EN 55032
