ADM809MAKS-REEL7

Supervisors Overview

The ADM809MAKS-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed as a microprocessor supervisor in an SC-70-3 package. It features a push-pull output and monitors a single input with threshold voltages of 2.5 V, 3 V, 3.3 V, or 5 V. The device operates within a supply voltage range up to 5.5 V and maintains an accuracy of 1.5%. Key electrical parameters include a reset delay time of 840 ms, a quiescent current of 60 uA, and an overvoltage threshold of 4.45 V. It functions reliably across a temperature range from -40 C to +125 C.

Supervisors Feature Summary

• Provides precise voltage supervision for microprocessor systems with configurable threshold options.
• Features a push-pull output stage for direct interface with digital logic.
• Operates with low power consumption suitable for battery-backed applications.

Supervisors Applications

• Microprocessor system reset circuits
• Portable equipment power management
• Battery-operated devices requiring voltage monitoring

Supervisors Procurement Notes

Verify the specific threshold voltage variant required (2.5 V, 3 V, 3.3 V, or 5 V) as the suffix indicates different trip points. Confirm availability status as the component may be subject to limited supply or discontinuation. Ensure the SC-70-3 package fits the target PCB layout constraints. Check RoHS compliance documentation for regulatory requirements.

Supervisors Selection Notes

Select this component when a fixed threshold supervisor with push-pull output is needed. Compare the 840 ms reset delay against system startup timing requirements. Consider the 60 uA quiescent current impact on total system power budget. Verify that the 5.5 V maximum supply voltage aligns with the monitored rail.

Supervisors Part Context

This part belongs to the ADM809 series of voltage supervisors from Analog Devices. It is distinct from other variants like the ADM809SAKSZ which has different threshold specifications. The REEL7 designation indicates tape and reel packaging for automated assembly.

Supervisors Replacement Considerations

Check for ADM809 variants with matching threshold voltages and push-pull outputs. Verify pin compatibility with the SC-70-3 package. Ensure equivalent reset delay and operating temperature ranges are met by potential substitutes.
