ADM1066ASUZ

Supervisors Overview

The ADM1066ASUZ is a Super Sequencer supervisory circuit manufactured by Analog Devices Inc., housed in a 48-lead TQFP surface-mount package. It monitors up to ten input voltages with configurable thresholds ranging from 573 mV to 14.4 V and includes auxiliary ADC inputs for margining control. The device features open collector/drain and push-pull outputs, a watchdog timer, and manual reset capability. It operates on a supply voltage between 2.7 V and 14.4 V, consumes 4.2 mA of operating current, and functions within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Configurable multi-supply monitoring with auxiliary analog-to-digital converter inputs for system margining
