ADM1816-R23ART-RL

Supervisors Overview

The ADM1816-R23ART-RL is a fixed-threshold voltage supervisor IC from Analog Devices. It provides a reset signal when the supply voltage drops below a specific level. The device features a fixed threshold voltage of 2.31V and a minimum reset timeout of 100ms. It operates within an extended temperature range of -40°C to +105°C. The component is housed in a surface-mount SOT-23-3 package, suitable for space-constrained designs requiring reliable power monitoring.

Supervisors Feature Summary

• Provides automatic system reset upon detection of undervoltage conditions
• Fixed threshold voltage ensures precise monitoring without external components
• Extended industrial temperature rating supports operation in harsh environments

Supervisors Applications

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

Supervisors Procurement Notes

Verify the exact suffix 'R23' confirms the 2.31V threshold variant. Confirm the 'ARTZ' or 'ART' designation matches the required RoHS compliance and tape-and-reel packaging specifications. Ensure the manufacturer source is authorized to guarantee authenticity for critical safety applications.

Supervisors Selection Notes

Select this part when a fixed 2.31V threshold is required for low-voltage systems. Compare against other ADM1816 variants with different thresholds if the supply rail differs. Consider the SOT-23-3 package size constraints and the need for a simple, non-programmable reset solution.

Supervisors Part Context

This component belongs to the ADM1816 family of microprocessor reset circuits. It serves as a dedicated voltage supervisory device designed to monitor single-rail power supplies. The family offers various threshold options to accommodate different logic levels and battery chemistries.

Supervisors Replacement Considerations

Check for ADM1816-R23ARTZ-RL for confirmed RoHS-compliant equivalents. Verify DS1816R-5+T&R only if the 3.06V threshold is acceptable for the application.
