DS1816-5/T&R

Supervisors Overview

The DS1816-5/T&R is a voltage supervisory circuit from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It features an open-drain output and monitors a single input channel with a threshold voltage of 4.62V. The device provides a reset delay time of 150ms and supports a maximum supply voltage of 5.5V. Operating within a temperature range of -40°C to +85°C, it is housed in a TO-92-3 package designed for through-hole installation.

Supervisors Feature Summary

• Provides power-failure detection capabilities
• Features manual reset functionality

Supervisors Applications

• Embedded system power monitoring
• Microcontroller reset generation
• Portable electronic device supervision

Supervisors Procurement Notes

Verify component status as this part number may be discontinued or subject to limited availability. Confirm package type and lead times with authorized distributors. Ensure RoHS compliance matches project requirements. Check for obsolescence notices before finalizing design-in decisions.

Supervisors Selection Notes

Select this component when through-hole mounting is required for voltage supervision. Compare against surface-mount alternatives like the DS1816R-5+T&R if PCB space is constrained. Verify that the 4.62V threshold aligns with the monitored rail voltage. Consider the 150ms reset delay duration relative to system startup timing requirements.

Supervisors Part Context

This component belongs to the DS1816 family of simple reset circuits. It serves as a dedicated power management IC for ensuring stable operation of digital logic by detecting under-voltage conditions. The EconoReset series offers cost-effective supervision solutions for basic power integrity needs.

Supervisors Replacement Considerations

Consider the DS1816R-5+T&R for surface-mount applications requiring similar electrical characteristics. Verify pin compatibility and threshold voltage matching when substituting with other DS1816 variants.
