ADM1812-5ART-REEL

Supervisors Overview

The ADM1812-5ART-REEL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It provides a reset signal for systems with supply voltages up to 5.5 V. The device features a fixed threshold voltage of 4.62 V and a typical reset delay time of 250 ms. It is housed in a SOT-23-3 surface-mount package. The output configuration supports open-drain or push-pull modes, allowing flexibility in interface design. The component operates within a standard temperature range and includes internal hysteresis to prevent false triggering during power transitions.

Supervisors Feature Summary

• Provides reliable system reset signals upon power-up or brown-out conditions
• Features internal hysteresis to ensure noise immunity during voltage transitions
• Supports flexible interface integration through selectable output drive configurations

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered equipment supervision
• Portable electronic device reset generation

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm exact packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead-free material declarations prior to procurement. Ensure the sourcing channel provides valid manufacturer traceability for quality assurance purposes.

Supervisors Selection Notes

Select this component when a fixed 4.62 V threshold is required for single-supply monitoring. Consider the SOT-23-3 package constraints for space-limited designs. Evaluate the 250 ms delay requirement against system startup timing needs. Verify that the available output drive types meet the load requirements of the target logic family.

Supervisors Part Context

This part belongs to the ADM1812 series of microprocessor reset circuits from Analog Devices. The series offers various threshold voltages and package options to suit different application requirements. The ADM1812 variant specifically targets applications requiring precise voltage supervision with minimal external components.

Supervisors Replacement Considerations

Consult official cross-reference data for verified substitutes such as the ADM1812-5ARTZ-RL72. Ensure any replacement matches the electrical thresholds and package dimensions.
