ADM810MARTZ-REEL

Supervisors Overview

The ADM810MARTZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single power supply rail. It features a push-pull output and operates within a supply voltage range of 1 V to 5.5 V. The device provides a reset threshold of 4.38 V with an accuracy of 1.5%. It includes a fixed reset delay time of 240 ms and consumes a typical operating current of 60 uA. The component is housed in an SOT-23-3 surface-mount package and supports an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides high-level active reset signal via push-pull output for reliable logic interfacing
• Ensures precise voltage monitoring with 1.5% threshold accuracy across wide temperature ranges
• Maintains low power consumption suitable for battery-operated or energy-efficient systems

Supervisors Applications

• Microprocessor system supervision
• Portable equipment power management
• Industrial control board voltage monitoring

Supervisors Procurement Notes

Verify the exact suffix configuration against official Analog Devices documentation, as variations may exist between REEL7 and other packaging formats. Confirm RoHS compliance status and lead times through authorized distributors, noting that specific reel quantities and availability are subject to manufacturer updates. Ensure the part number matches the required threshold voltage and package type for your design.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor with a fixed 4.38 V threshold is required. It is suitable for applications needing a push-pull output without manual reset functionality. Consider the 60 uA quiescent current and 240 ms delay when designing timing-critical circuits. Verify compatibility with the target system's voltage levels and thermal requirements.

Supervisors Part Context

This part belongs to the ADM810 series of microprocessor supervisors from Analog Devices. The series offers various threshold voltages and packages to suit different monitoring needs. The MARTZ suffix indicates a specific threshold voltage and SOT-23-3 packaging variant within this family, distinguishing it from other ADM810 models with different reset delays or output types.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the ADM810 series or similar Analog Devices supervisors like the ADM809 or ADM811 if threshold voltages match. Verify that replacement parts offer identical push-pull outputs and comparable reset delay times to ensure circuit stability.
