DS1813-15+T

Supervisors Overview

The DS1813-15+T is a power supply support circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a voltage range of 4.75V to 5.5V and features a fixed threshold voltage of 4.13V. The device utilizes an open-drain or open-collector output for reset signaling, with a minimum reset timeout of 100ms. Designed for surface-mount installation in SOT-23 packages, it supports a pushbutton reset option and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors power supply status using precision temperature reference and comparator circuits
• Generates internal power-fail signals during out-of-tolerance conditions
• Maintains reset state for stabilization upon power return
• Supports manual reset generation via pushbutton input on the reset output

Supervisors Applications

• Power supply monitoring in embedded systems
• Processor reset management in microcontroller applications
• System supervision in industrial control equipment

Supervisors Procurement Notes

Verify component authenticity through authorized distributors. Confirm package type matches SOT-23 specifications. Ensure operating voltage aligns with 4.75V to 5.5V requirements. Check temperature rating suitability for -40°C to +85°C environments. Validate reset timeout characteristics against system stability needs.

Supervisors Selection Notes

Select based on fixed 4.13V threshold requirement. Consider SOT-23 package constraints for PCB layout. Evaluate pushbutton functionality necessity for manual reset operations. Verify compatibility with open-drain/open-collector interface requirements. Assess thermal performance within specified operating temperature range.

Supervisors Part Context

Part of Maxim's EconoReset family designed for cost-effective power supervision. Combines voltage monitoring with manual reset capability in compact packaging. Targets applications requiring reliable system initialization without complex external components.

Supervisors Replacement Considerations

DS1813 variants offer similar functionality with different threshold voltages. DS1233 provides comparable reset supervision without pushbutton feature. DS1818 serves as alternative for 3.3V systems. Verify pinout compatibility before substitution.
