ADM1168ASTZ

Overview

The ADM1168ASTZ is a Super Sequencer integrated circuit manufactured by Analog Devices Inc., designed for complex power management applications. It operates within a supply voltage range of 3V to 14.4V and draws a supply current of 4.2 mA. The device is housed in a 32-LQFP (7x7 mm) surface-mount package with an operating temperature range of -40°C to +85°C. It functions as both a power supervisor and a sequencer, featuring integrated non-volatile fault recording capabilities for system diagnostics.

Feature Summary

• Integrates super sequencer functionality with programmable power sequencing logic
• Includes built-in non-volatile memory for persistent fault recording and system history tracking
• Provides comprehensive power monitoring and supervision for multiple rails

Applications

• Complex server and storage system power management
• Industrial equipment requiring robust power sequencing
• Telecommunications infrastructure power supplies

Procurement Notes

Verify the specific suffix ASTZ corresponds to the required temperature grade and packaging format. Confirm that the 32-LQFP footprint matches the target PCB design. Ensure compatibility with the intended input voltage range of 3V to 14.4V. Check for any recent product change notices or end-of-life announcements from Analog Devices prior to finalizing procurement plans.

Selection Notes

Select this component when simultaneous power sequencing and detailed fault logging are required. It is suitable for designs needing supervision across multiple voltage rails within the specified input range. Consider the 32-LQFP package constraints during layout. Evaluate if the integrated non-volatile feature meets diagnostic requirements without external memory components.

Part Context

This part belongs to the Super Sequencer family from Analog Devices, which focuses on advanced power management solutions. It complements other PMIC devices by handling the critical timing and monitoring aspects of multi-rail power systems. The series is commonly used in high-reliability applications where power integrity and fault traceability are essential.
