Working Principle

The ADM1065ASUZ is designed to monitor and control voltages, temperatures, and currents across multiple power rails and pin pairs. It allows designers to easily set margin, and can trip a fault in a wide range of operating conditions, quickly and reliably. The device supports sequencing and tracking of multiple power rails to enable advanced, automated startup and shut down of power supplies. The device also provides thermally-thresholded shutdown and monitoring functionality, enabling designers to protect systems from overtemperature and improve system reliability.Finally, the device helps designers to differentiate their products with the addition of real-time power monitoring capabilities. The device integrates a high resolution ADC, enabling power consumption levels to be monitored over time in order to improve power consumption efficiency.

In addition, the device includes on-die thermal monitoring and protection, providing protection against thermal runaway conditions. The thermal monitor can be used to trip a fault signal or take corrective action by controlling fan speeds or other measures. By combining these features with a robust fault signal processing system, the ADM1066ASUZ ensures reliable power supply and monitoring solutions for a variety of consumer, industrial, and automotive applications.
