ADM1067ASUZ

Supervisors Overview

The ADM1067ASUZ is a Super Sequencer and Monitor integrated circuit manufactured by Analog Devices Inc. It features ten monitored inputs with configurable thresholds, supporting voltage ranges from 573 mV to 14.4 V. The device includes a watchdog timer, manual reset capability, and auxiliary analog-to-digital converter (ADC) inputs for margining control. It operates within a supply voltage range of 2.7 V to 14.4 V and functions across an industrial temperature range of -40°C to +85°C. Packaged in a 48-lead TQFP, it provides open-drain and push-pull outputs for precise power sequencing.

Supervisors Feature Summary

• Configurable threshold monitoring for up to ten independent power rails
• Integrated watchdog timer with programmable timeout functionality
• Manual reset input for system recovery control
• Auxiliary ADC inputs enabling real-time voltage margining

Supervisors Applications

• Complex multi-rail power sequencing in server platforms
• Voltage supervision in telecommunications infrastructure equipment
• Power management in industrial automation controllers
• System supervisor design for embedded computing systems

Supervisors Procurement Notes

Verify the specific suffix ASUZ corresponds to the tape-and-reel packaging variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected package matches the target PCB footprint specifications exactly. Cross-reference the latest datasheet revision to validate pinout compatibility with existing designs.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous supervision of multiple voltage rails with distinct threshold requirements. The inclusion of auxiliary ADC inputs makes it suitable for applications needing active voltage margining capabilities. Consider the 48-lead TQFP package constraints regarding board space and thermal dissipation requirements during the layout phase.

Supervisors Part Context

This part belongs to the ADM106x family of Super Sequencers, which are designed for comprehensive power management in complex electronic systems. The series offers scalable solutions for monitoring and sequencing power rails in demanding environments. The ADM1067 variant specifically adds margining controls via auxiliary ADCs compared to earlier models in the lineup.

Supervisors Replacement Considerations

Direct substitutes include the ADM1066ASUZ and ADM1065ASUZ. Verify functional differences such as the presence or absence of manual reset inputs and auxiliary ADC channels before swapping components.
