ADM1169ASTZ-RL7

Overview

The ADM1169ASTZ-RL7 is a programmable supervisor sequencer IC from Analog Devices, designed for complex power supply monitoring and sequencing applications. It features an LQFP-32 (7x7) package and operates within a supply voltage range of 3V to 14.4V across an industrial temperature range of -40°C to +85°C. The device monitors up to eight inputs with configurable thresholds, including options such as 573 mV to 1.375 V, 1.25 V to 3 V, 2.5 V to 6 V, and 6 V to 14.4 V. It provides open collector/drain and push-pull outputs, includes a manual reset function, and integrates a watchdog timer for system reliability.

Feature Summary

• Configurable supervisory and sequencing capabilities for multi-rail power systems
• Integrated watchdog timer and manual reset functionality
• Supports both open collector/drain and push-pull output configurations

Applications

• Power supply monitor and sequencer in embedded systems
• Complex power management in industrial equipment
• System supervision in communication infrastructure

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix RL7 indicates tape and reel packaging if required by assembly processes. Check current availability status as supply may be limited or subject to discontinuation notices. Ensure compatibility with existing board designs regarding pinout and thermal requirements before procurement.

Selection Notes

Select this component when designing systems requiring precise control over multiple power rails. It is suitable for applications needing configurable voltage thresholds and flexible output drive types. Consider the LQFP-32 package size for space-constrained designs. Evaluate the need for integrated watchdog and manual reset features against external components to simplify the bill of materials.

Part Context

The ADM1169 belongs to the Super Sequencer family from Analog Devices, offering single-chip solutions for supply monitoring. It complements other power management ICs by handling complex sequencing logic that discrete components cannot efficiently manage. This series is targeted at high-reliability applications where power integrity is critical.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with any alternative devices regarding threshold ranges, output types, and package dimensions.
