ADM1168ASTZ-RL7

Overview

The ADM1168ASTZ-RL7 is a Super Sequencer integrated circuit manufactured by Analog Devices Inc., designed for complex power management sequences. 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 integrates non-volatile fault recording capabilities, allowing for the retention of system status data across power cycles.

Feature Summary

• Integrates non-volatile memory for persistent fault recording and system status monitoring
• Provides programmable sequencing control for multi-rail power systems
• Features manual reset input capability for controlled system recovery

Applications

• Multi-rail server power distribution units
• Industrial automation controller power sequencing
• Telecommunications infrastructure power management

Procurement Notes

Verify the specific suffix RL7 against the manufacturer's official datasheet to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the component matches the required 32-LQFP footprint and thermal characteristics for your PCB layout. Cross-reference the part number with Analog Devices documentation to confirm active status and any recent design changes or obsolescence notices.

Selection Notes

Select this component when a system requires precise, programmable sequencing of multiple voltage rails combined with diagnostic fault logging. It is suitable for applications needing non-volatile memory to track power-up/down events without external storage. Consider the 32-pin LQFP package constraints and the 3V to 14.4V input range compatibility with your primary supply rail.

Part Context

The ADM1168 belongs to Analog Devices' Super Sequencer family, which focuses on managing complex power-up and power-down sequences in demanding electronic environments. This series is engineered to handle the synchronization of multiple power domains, ensuring stable operation during transient conditions and providing robust monitoring for critical infrastructure applications.

Replacement Considerations

Consult Analog Devices official documentation for verified cross-reference part numbers. Do not substitute based on generic pinout similarities; verify functional equivalence and interface compatibility through manufacturer-approved sources.
