ADM1812-5ARTZ-RL7

Supervisors Overview

The ADM1812-5ARTZ-RL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.3 V to 5.5 V and features a fixed threshold voltage of 4.63 V for power monitoring. The device provides a push-pull output and includes a reset delay time of 200 ms. It is housed in a compact SOT-23-3 surface-mount package and supports an operating temperature range from -40°C to +85°C. This component functions as a dedicated reset generator without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Provides automatic system reset when monitored voltage drops below the specified threshold
• Features a fixed 4.63 V threshold voltage for precise power supervision
• Delivers a push-pull output signal for direct interface with digital logic

Supervisors Applications

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

Supervisors Procurement Notes

Verify current availability status as distribution channels may indicate limited stock or discontinuation. Confirm RoHS compliance details through official manufacturer documentation prior to integration. Ensure the specific suffix matches design requirements for packaging format. Cross-reference datasheet revisions to validate electrical characteristics against current production standards.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-input voltage monitoring. The SOT-23-3 package suits space-constrained designs. Verify that the 200 ms reset delay aligns with system startup timing requirements. Consider the absence of manual reset functionality if user intervention is necessary for recovery.

Supervisors Part Context

This part belongs to the ADM1817/ADM1818 series of supervisory circuits from Analog Devices. These devices are designed for low-power applications requiring reliable voltage monitoring. The RL7 suffix indicates reel packaging for automated assembly processes. The series typically offers various threshold options to accommodate different standard voltage rails.
