ADM810ZART-REEL7

Supervisors Overview

The ADM810ZART-REEL7 is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1V to 5.5V and features a push-pull/totem pole output configuration with active-high reset assertion. The device provides a fixed reset threshold voltage of 2.63V and includes a minimum reset timeout delay of 140ms. It is housed in a compact SOT-23-3 surface-mount package and is rated for an industrial operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable power-on reset functionality with a fixed 2.63V threshold for monitoring single power rails.
• Features a push-pull output stage capable of driving digital logic interfaces directly without external pull-up resistors.
• Ensures system stability through a guaranteed minimum reset timeout delay, allowing sufficient time for power supplies to stabilize.

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Battery-powered portable electronic devices requiring low standby current
• Industrial control systems operating in extended temperature environments

Supervisors Procurement Notes

Verify the specific suffix 'Z' indicates lead-free compliance status according to manufacturer documentation. Confirm that the 'REEL7' designation corresponds to the correct tape and reel quantity for automated assembly processes. Cross-reference the exact part number against official Analog Devices databases to ensure availability and obsolescence status prior to procurement planning.

Supervisors Selection Notes

Select this component when a fixed 2.63V threshold is required for standard 3.3V or 5V logic systems. The SOT-23-3 package is suitable for space-constrained designs. Ensure the application does not require manual reset inputs or watchdog timers, as this specific variant lacks those features. Verify that the 140ms timeout meets the system's power-up sequence requirements.

Supervisors Part Context

This component belongs to the ADM810 series of simple reset generators designed for cost-sensitive applications. It serves as a fundamental building block for power management in embedded systems where complex supervisory features are unnecessary. The series offers various threshold voltages and packages to accommodate different rail monitoring needs across consumer and industrial electronics.

Supervisors Replacement Considerations

Direct substitutes include other ADM810 variants with identical pinouts but different threshold voltages (e.g., ADM810LART for 4.63V). Alternative families such as MAX809 or TPS38xx may offer functional equivalents but require verification of electrical parameters and package compatibility.
