The Monitoring of Pixel System (MOPS) chip for the Detector Control System of the ATLAS ITk Pixel Detector

The ATLAS experiment will get a new inner tracker (ITk) during the phase II upgrade. innermost part is called Pixel Detector. A Detector Control System (DCS) being developed to provide control and monitoring of ITk pixel detector. Monitoring (MOPS) chip an Application Specific Integrated Circuit (ASIC) foreseen in DCS independently monitor voltage temperature across modules which constitute front-end electronics responsible for tracking data readout. by Bergische Universität Wuppertal collaboration with Fachhochschule Dortmund. need be monitored are powered serially chain. MOPS has 12-bit ADC can read up 34 channels. Controller Area Network (CAN) CANopen protocols used communication. final required radiation hard ionizing dose 500 Mrad. In this paper, functionality discussed, some results from first version presented as well brief overview second version.
