ADM812ZART-REEL7

Supervisors Overview

The ADM812ZART-REEL7 is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.32 V. The device provides an active high output with a reset delay time of 560 ms and includes manual reset functionality. It lacks a watchdog timer or battery backup switch. The component is housed in a lead-free SOT-143-4 package, suitable for surface mount installation, and supports an operating temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

• Provides reliable voltage monitoring with a fixed 2.32 V threshold for critical power supply supervision
• Features active high output logic and integrated manual reset capability for system control
• Designed for low-power applications with minimal quiescent current consumption

Supervisors Applications

• Portable equipment requiring precise voltage supervision
• Battery-powered systems needing low standby current
• Microprocessor reset circuits in embedded designs

Supervisors Procurement Notes

Verify the specific suffix ZART against official Analog Devices documentation to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status and lead-free certification directly with the manufacturer or authorized distributors. Ensure the reel quantity matches project requirements as packaging formats may vary. Cross-reference the part number with the latest datasheet to validate electrical characteristics before procurement.

Supervisors Selection Notes

Select this component when a fixed 2.32 V threshold is required for single-supply monitoring. The active high output and manual reset feature suit applications needing direct user intervention or specific logic levels. Consider the SOT-143-4 package for space-constrained PCB layouts. Verify that the 560 ms reset delay aligns with system startup timing requirements and that the operating temperature range meets environmental conditions.

Supervisors Part Context

The ADM812 series comprises reliable voltage monitoring devices designed for general-purpose power supply supervision. This specific model belongs to the ADM812 family, which offers various threshold options. The ZART designation indicates a specific threshold voltage and package configuration within the broader product line, ensuring compatibility with standard surface mount assembly processes.

Supervisors Replacement Considerations

Check for ADM812 variants with different threshold voltages if the 2.32 V level is unsuitable. Verify pinout compatibility with alternative supervisors in the same SOT-143-4 package. Ensure replacement parts maintain similar reset delay times and output logic polarity.
