ADM809MAKS-REEL

Supervisors Overview

The ADM809MAKS-REEL is a voltage supervisory circuit from the Analog Devices ADM809 series, designed for microprocessor supervision. It operates within a supply voltage range up to 5.5 V and features a push-pull output type with no manual reset or watchdog timer capabilities. The device monitors a single input and provides threshold voltages of 2.5 V, 3 V, 3.3 V, or 5 V. It exhibits a reset delay time of 840 ms and an overvoltage threshold of 4.45 V. Operating current is specified at 60 uA. The component is housed in an SC-70-3 package and supports surface mount installation. It functions reliably across a temperature range from -40 C to +125 C.

Supervisors Feature Summary

• Provides voltage supervision for microprocessor systems with selectable threshold options
• Features a compact SC-70-3 surface-mount package for space-constrained designs
• Delivers a push-pull output signal without requiring manual reset or external watchdog components

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system voltage supervision
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with design requirements. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Cross-reference the exact part number with official Analog Devices documentation to validate pinout and electrical characteristics before procurement.

Supervisors Selection Notes

Select this component when a low-power, single-input voltage supervisor is required for microprocessor applications. Consider the 840 ms reset delay and available threshold voltages to match system timing needs. Ensure the operating temperature range meets environmental specifications. Verify that the SC-70-3 package fits the board layout constraints.

Supervisors Part Context

This part belongs to the ADM809 family of supervisory circuits manufactured by Analog Devices Inc. The family offers various threshold voltages and packages to suit different power management needs. The ADM809MAKS variant specifically utilizes the SC-70-3 package and includes a 4.45 V overvoltage threshold characteristic.

Supervisors Replacement Considerations

Check for ADM809 variants with identical thresholds and packages. Verify functional equivalence with other single-input supervisors from Analog Devices or competitors. Ensure replacement parts maintain the same operating temperature range and output configuration.
