DS1813R-15-U+

Supervisors Overview

The DS1813R-15-U+ is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.0V to 6.0V and features a fixed threshold voltage of 4.53V. The device provides an active-low reset output with a minimum timeout of 140ms. It is housed in a compact SOT-23-3 package and supports operation across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides reliable system reset via active-low open-drain output
• Integrates manual reset input for user-initiated system restarts
• Ensures power-on reset functionality upon power-up

Supervisors Applications

• Microcontroller and microprocessor power supervision
• Battery-powered equipment requiring low standby current
• Industrial control systems operating in harsh environments

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and temperature rating. Check for RoHS compliance documentation if environmental regulations apply to your assembly process. Ensure availability status aligns with production timelines as supply constraints may affect lead times.

Supervisors Selection Notes

Select this component when a fixed 4.53V threshold is appropriate for the target logic level. The SOT-23-3 package suits space-constrained designs. Verify that the 140ms minimum reset timeout meets the system's initialization requirements. Consider the manual reset pin utility if hardware restart capability is necessary for the application.

Supervisors Part Context

This part belongs to the Maxim Integrated EconoReset family, designed for cost-sensitive applications requiring basic power management. It complements other supervisors in the series offering different thresholds or packages. The product line focuses on providing essential reset functions without complex configuration interfaces.

Supervisors Replacement Considerations

Consult official datasheets for cross-reference candidates such as the DS1813R-15-T&R for tape-and-reel packaging variants. Verify electrical compatibility including threshold voltage and reset timeout characteristics before substitution.
