ADM812LARTZ-REEL7

Supervisors Overview

The ADM812LARTZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single input voltage. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 4.63 V. The device provides an active low output signal with a reset delay time of 560 ms. Packaged in a SOT-143-4 surface-mount format, it supports manual reset functionality but lacks a watchdog timer or battery backup switch. The component is rated for operation between -40°C and +125°C.

Supervisors Feature Summary

• Provides active low reset signal generation based on monitored input voltage levels
• Includes manual reset capability for system control flexibility
• Operates across extended industrial temperature ranges

Supervisors Applications

• Power supply monitoring in embedded systems
• Microcontroller reset generation in industrial equipment
• Voltage supervision in automotive electronics

Supervisors Procurement Notes

Verify the specific suffix 'REEL7' indicates tape and reel packaging when ordering. Confirm the manufacturer part number matches exactly as Analog Devices Inc. sources this component. Check current availability status as distribution may be limited. Ensure the package type SOT-143-4 fits the target PCB layout constraints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for power rail supervision. Consider the 560 ms reset delay duration against system startup timing requirements. Evaluate the SOT-143-4 package size against available board space. Verify that the active low output polarity aligns with the receiving logic interface design specifications.
