ADM1166ACPZ

Overview

The ADM1166ACPZ is a programmable supervisor sequencer IC manufactured by Analog Devices Inc. It operates within an input voltage range of 3V to 14.4V and features ten monitored inputs with threshold voltages spanning 573mV to 6V. The device provides open collector/drain and push-pull outputs, includes a watchdog timer, and offers a reset delay time of 400ms. It maintains accuracy of 0.5% and functions at a supply current of 4.2mA across temperatures from -40°C to +85°C.

Feature Summary

• Configurable supervisory sequencing for multi-supply systems
• Integrated watchdog timer functionality
• Supports both open collector and push-pull output configurations

Applications

• Power monitoring in complex electronic systems
• Voltage sequence generation for processor boards
• System supervision for industrial equipment

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm package integrity upon receipt as the unit utilizes surface mount technology. Ensure storage conditions comply with humidity sensitivity requirements prior to assembly. Cross-reference ordering information with official manufacturer documentation to validate part specifications.

Selection Notes

Select this component when designing systems requiring precise voltage sequencing and supervision. Evaluate compatibility with target supply rails ranging up to 14.4V. Consider the ten-input capacity for comprehensive system monitoring needs. Assess thermal performance requirements against the specified operating temperature range.

Part Context

This device belongs to the Super Sequencer family designed for power management applications. It serves as a central control element for managing power-up and power-down sequences in multi-rail environments. The component integrates multiple supervisory functions into a single chip to reduce board space and design complexity.

Replacement Considerations

Evaluate the ADM1166ASUZ as a potential alternative based on pin compatibility and functional equivalence. Verify package differences between LFCSP-40 and TQFP formats during transition planning.
