ADM1066ACPZ

Supervisors Overview

The ADM1066ACPZ is a Super Sequencer supervisory circuit by Analog Devices, housed in a 40-pin LFCSP package. It supports a supply voltage range of 3V to 14.4V and monitors up to ten inputs. The device features programmable reset functionality with a typical delay of 100μs. Threshold voltages span from 573mV to 14.4V across multiple ranges. Operating temperature extends from -40°C to +85°C, with a maximum operating current of 4.2mA.

Supervisors Feature Summary

• Configurable supervisory and sequencing capabilities for multi-supply systems
• Integrated margining control and auxiliary analog-to-digital converter inputs
• Supports open collector/drain and push-pull output configurations

Supervisors Applications

• Power monitoring and sequencing in complex electronic systems
• Margining control applications requiring auxiliary ADC inputs
• Supervisory circuits for processor and memory power rails

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the component matches the required 40-pin LFCSP form factor. Confirm that the threshold voltage ranges align with system requirements before integration.

Supervisors Selection Notes

Select this component when a single-chip solution for supply monitoring and sequencing is required. Consider the auxiliary ADC inputs if margining control is necessary. Verify that the 10-input capacity meets the design's supervision needs and that the LFCSP package fits the board layout constraints.

Supervisors Part Context

The ADM1066 belongs to the Super Sequencer family designed for robust power management. It integrates monitoring, sequencing, and margining functions into one device. This consolidation reduces component count and simplifies design complexity for multi-rail power architectures.

Supervisors Replacement Considerations

The ADM1066ASUZ serves as a package variant within the same functional family. Verify compatibility regarding the TQFP-48 versus LFCSP-40 footprint and manual reset availability differences.
