ADM810MARTZ-REEL7

Supervisors Overview

The ADM810MARTZ-REEL7 is a single-channel voltage supervisor manufactured by Analog Devices Inc., designed to monitor power supply integrity in electronic systems. It operates within a supply voltage range of 1 V to 5.5 V and features a push-pull/totem pole output configuration with active-high reset assertion. The device provides a minimum reset timeout of 140 ms, ensuring stable system recovery during power-up or brown-out events. It is housed in a compact SOT-23-3 surface-mount package and supports an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Monitors a single voltage input channel for under-voltage conditions
• Provides a high-active push-pull reset signal for direct logic interfacing
• Ensures reliable system initialization through a defined minimum reset delay

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Battery-operated equipment requiring low standby current
• Embedded systems needing brown-out protection

Supervisors Procurement Notes

Verify the specific threshold voltage variant required for the application, as the ADM810 series includes multiple options (e.g., 2.63V, 2.93V, etc.). Confirm that the SOT-23-3 package aligns with the PCB footprint constraints. Ensure the selected part number suffix matches the desired reset timeout and voltage accuracy specifications documented in the official datasheet.

Supervisors Selection Notes

Select this component when a simple, cost-effective solution for monitoring a single rail is required. Consider the trade-off between the fixed reset timeout and the need for precise voltage thresholds. Evaluate the SOT-23-3 package size against available board space. Verify that the operating temperature range meets the environmental requirements of the target deployment scenario.

Supervisors Part Context

This component belongs to the ADM810 family of microprocessor supervisors, which are designed for general-purpose power management applications. The family offers various threshold voltages and packages to accommodate different system architectures. The ARTZ suffix indicates a specific tape-and-reel packaging format suitable for automated assembly processes.
