DS1813-5+T&R

Supervisors Overview

The DS1813-5+T&R is a supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for power supply monitoring applications. It operates as a 5V EconoReset device featuring an integrated pushbutton reset option. The component utilizes a precision temperature reference and comparator circuit to monitor the VCC status. When an out-of-tolerance condition is detected, it generates an internal power-fail signal to force the reset output active. Upon return to tolerance, the reset remains active for approximately 150ms to allow stabilization. It supports manual reset generation via a pushbutton connected to the reset output.

Supervisors Feature Summary

• Monitors power supply voltage status using a precision temperature reference and comparator circuit
• Generates internal power-fail signals to force reset active during out-of-tolerance conditions
• Includes a dedicated pushbutton reset option that triggers a reset upon release
• Maintains reset output low for approximately 150ms to ensure processor and power supply stabilization

Supervisors Applications

• Power supply support circuits requiring voltage monitoring
• Systems utilizing pushbutton reset mechanisms
• Processor reset generation in embedded designs

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance details and lead times with suppliers. Check for alternative sourcing options given limited availability. Ensure packaging specifications match system requirements. Validate datasheet revisions against current manufacturing standards.

Supervisors Selection Notes

Select this component for applications requiring simple, low-cost power supervision with manual reset capability. Consider the fixed 5V operating threshold and TO-92 package constraints. Evaluate thermal performance within the specified -40°C to +85°C range. Assess compatibility with existing reset logic requirements before integration.
