ADM812MARTZ-REEL7

Supervisors Overview

The ADM812MARTZ-REEL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc., designed to monitor voltage levels in single-supply systems. It features a push-pull active high output and includes a manual reset input for user-initiated system resets. The device operates within a supply voltage range of 1.2 V to 5.5 V, with a typical threshold voltage of 4.63 V. It offers a reset timeout delay of 560 ms and maintains low quiescent current consumption of 15 uA. The component is housed in an SOT-143-4 surface-mount package and supports operation across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a manual reset button interface allowing direct user control over the reset state.
• Provides a push-pull active high output driver capable of sourcing and sinking current directly.
• Ensures reliable power-up sequencing with a fixed reset timeout delay period.
• Maintains ultra-low standby current consumption suitable for battery-powered applications.

Supervisors Applications

• Microprocessor and microcontroller power supply monitoring
• Battery-operated portable electronic devices
• Industrial control system voltage supervision
• Embedded system power management circuits

Supervisors Procurement Notes

Verify the specific suffix 'M' indicates the 4.63 V threshold variant when sourcing replacements. Confirm the 'ARTZ' designation corresponds to the SOT-143-4 package and reel packaging format. Check manufacturer documentation for RoHS compliance status and lead-free specifications prior to integration into final assemblies.

Supervisors Selection Notes

Select this component when a manual reset function is required alongside automatic power-on reset capabilities. Choose based on the 4.63 V threshold requirement for standard 5 V logic systems. Consider the SOT-143-4 footprint constraints and the 15 uA quiescent current specification for power-sensitive designs compared to higher current alternatives.

Supervisors Part Context

This part belongs to the ADM812 series of voltage supervisors from Analog Devices. It complements other variants like the ADM812LARTZ which may differ in threshold voltage or package type. The series focuses on providing robust reset signals for digital logic families operating at standard voltage levels.

Supervisors Replacement Considerations

Direct substitutes include the ADM812LARTZ-REEL7 if threshold voltage differences are acceptable. Verify pinout compatibility between SOT-143-4 packages before swapping. Cross-reference datasheets for identical reset timeout and quiescent current specifications.
