ADM810RART-REEL

Supervisors Overview

The ADM810RART-REEL7 is a single-channel voltage supervisor IC from Analog Devices, designed for simple reset and power-on reset applications. It features a push-pull/totem pole output with active-high reset assertion. The device monitors a single input voltage against a threshold of 2.63V. Key electrical parameters include a minimum reset timeout of 140ms, a maximum supply voltage of 5.5V, and an operating range from 1V to 5.5V. It operates within a temperature range of -40°C to +125°C and is housed in a surface-mount SOT-23-3 package.

Supervisors Feature Summary

• Provides automatic system reset upon detection of under-voltage conditions relative to the specified threshold.
• Features a push-pull output stage capable of driving digital logic inputs directly without external pull-up resistors.
• Includes a guaranteed reset pulse width to ensure adequate delay for power supply stabilization before asserting reset.

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered system supervision
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the exact suffix (e.g., REEL7) as it denotes specific packaging configurations. Confirm availability status as this component may be discontinued or subject to limited supply. Ensure the 2.63V threshold aligns with the target system voltage requirements. Cross-reference the SOT-23-3 footprint with PCB design constraints.

Supervisors Selection Notes

Select this component when a fixed 2.63V threshold is required for low-voltage systems. Consider the 140ms minimum timeout for applications requiring rapid reset assertion after power stability. Evaluate the SOT-23-3 package size against board space limitations. Compare quiescent current specifications if battery life is critical, noting variations across similar family members.

Supervisors Part Context

This part belongs to the ADM810 series of voltage supervisors manufactured by Analog Devices. These devices are engineered for reliable operation in harsh environments, supporting wide temperature ranges. The series typically offers various threshold voltages and package options to accommodate diverse embedded design needs.

Supervisors Replacement Considerations

Public confirmed substitutes include MAX810REXR+T and ADM810TARTZ-REEL7. Verify pin compatibility and threshold voltage accuracy when substituting. Check for differences in reset timeout characteristics and output drive strength.
