ADM811LARTZ-REEL7

Supervisors Overview

The ADM811LARTZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor reset generation. It operates within a supply voltage range of 1.2 V to 5.5 V and features a manual reset input. The device utilizes an SOT-143-4 surface-mount package and provides a push-pull output type. Key electrical parameters include a threshold voltage of 4.5 V to 4.75 V, an overvoltage threshold of 4.72 V, and a reset delay time of 560 ms. It consumes 15 uA of operating current and supports power dissipation up to 200 mW across an industrial temperature range of -40 C to +85 C.

Supervisors Feature Summary

• Integrates manual reset functionality for controlled system initialization
• Provides precise voltage supervision with defined threshold levels
• Features low quiescent current consumption for power efficiency
• Delivers active push-pull output signal for direct logic interfacing

Supervisors Applications

• Microprocessor reset generator circuits
• Voltage monitoring in portable electronic devices
• Power management systems requiring supervised startup
• Industrial control boards needing manual reset capability

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance details as documentation indicates variable reporting. Ensure the specific suffix matches design requirements for tape and reel packaging. Cross-reference datasheet revisions to validate electrical characteristics against current production standards before integration into final hardware designs.

Supervisors Selection Notes

Select this component when a fixed threshold near 4.5 V is required for 5 V logic systems. The manual reset feature distinguishes it from automatic-only supervisors. Consider the SOT-143-4 footprint for space-constrained PCB layouts. Evaluate the 560 ms delay against system startup timing requirements to ensure adequate power stabilization before processor release.

Supervisors Part Context

This part belongs to the ADM811 series of voltage supervisors from Analog Devices. It shares architectural similarities with other members like the ADM811SARTZ but differs in threshold voltage specifications. The series is characterized by low power operation and compact packaging options suitable for modern surface-mount assembly processes in consumer and industrial electronics.
