DS1813-15+

Supervisors Overview

The DS1813-15+ is a single-channel power supply support circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as a fixed-threshold supervisor with an integrated pushbutton reset option, designed for 5V systems. The device monitors voltage levels and generates a reset signal when the supply drops below the threshold. It operates within a temperature range of -40°C to +85°C and is available in compact surface-mount packages such as SOT-23-3.

Supervisors Feature Summary

• Integrated pushbutton reset functionality allows manual system control alongside automatic voltage monitoring
• Fixed threshold supervision ensures reliable reset generation without external programming components
• Compact surface-mount packaging facilitates space-constrained board designs

Supervisors Applications

• Embedded processor and controller power management
• Microcontroller system supervision
• Smart socket SRAM backup circuits

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package type matches design requirements. Check for RoHS compliance status if environmental regulations apply. Ensure operating temperature range aligns with final application conditions. Validate pinout compatibility before integration.

Supervisors Selection Notes

Select this component for applications requiring simple, fixed-voltage supervision with manual override capability. Consider the SOT-23-3 package for limited board space. Evaluate thermal performance against the specified operating temperature range. Compare against other EconoReset variants if different thresholds are needed.

Supervisors Part Context

Part of the Maxim Integrated EconoReset family, which provides cost-effective power supply monitoring solutions. The DS1813 series includes variants with different thresholds and features. This specific model targets 5V systems with pushbutton integration, distinguishing it from basic reset supervisors.

Supervisors Replacement Considerations

DS1813-15-U+ offers identical electrical characteristics in a different package variant. DS1233 provides similar 5V supervision but lacks the pushbutton feature. Verify pinout and functional equivalence before substitution.
