ADM1066ASUZ-REEL

Supervisors Overview

The ADM1066ASUZ-REEL is a Super Sequencer with Margining Control and Auxiliary ADC Inputs manufactured by Analog Devices Inc. It is housed in a TQFP-48 surface-mount package. The device monitors up to 10 supply inputs with thresholds ranging from 573 mV to 1.375 V, 1.25 V to 3 V, 2.5 V to 6 V, and 6 V to 14.4 V. Overvoltage thresholds are set at 800 mV, 1.75 V, 3.5 V, and 8.4 V. It operates on a power supply voltage between 2.7 V and 14.4 V, consuming 4.2 mA of working current. The component supports manual reset, includes a watchdog timer, and features open collector/drain and push-pull outputs.

Supervisors Feature Summary

• Integrates a sequencing engine for state machine control of programmable driver outputs based on input events.
• Provides complete voltage-margining solution using six 8-bit voltage output DACs for closed-loop supply adjustment.
• Includes a 12-bit auxiliary ADC and five dual-function general-purpose logic inputs for system monitoring.

Supervisors Applications

• Supply monitoring and sequencing in multiple-supply systems
• Closed-loop margining systems for DC-to-DC converters
• Complex board power-up and power-down sequence control

Supervisors Procurement Notes

Verify the specific suffix REEL7 against official documentation to confirm reel quantity and tape specifications. Confirm that the TQFP-48 package matches the target PCB footprint. Check the lifecycle status as sources indicate potential end-of-life or obsolescence warnings. Ensure compatibility with the required SMBus interface and voltage levels before integration.

Supervisors Selection Notes

Select this component when a single-chip solution for supervising up to ten supplies is required. It is suitable for applications needing precise voltage margining via integrated DACs. Consider the TQFP-48 package size and the need for manual reset functionality. Verify that the operating temperature range of -40°C to +85°C meets the environmental requirements.

Supervisors Part Context

The ADM1066ASUZ-REEL belongs to the ADM1066 series of Super Sequencers. It is part of Analog Devices' portfolio of power management ICs designed for complex multi-rail power architectures. This specific variant uses a reel packaging format, distinguishing it from tray-packaged equivalents like the ADM1066ASUZ.
