DS1813-15

Supervisors Overview

The DS1813-15 is a single-channel voltage supervisor IC from the EconoReset family, manufactured by Analog Devices Inc./Maxim Integrated. It provides a reset signal for microprocessors and logic circuits when supply voltage drops below a threshold. The device features an integrated pushbutton input for manual reset control. It operates within a supply voltage range of 4.75V to 5.25V, with a specific trip point of 4.13V. The output is configured as an open-drain or open-collector type, ensuring low-active reset assertion. The component supports a minimum reset timeout of 100ms and functions across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a manual pushbutton switch for user-initiated system resets without external components.
• Provides reliable power-fail detection with a fixed threshold voltage for stable operation.
• Features an open-drain/reset output compatible with various digital logic families.

Supervisors Applications

• Microprocessor system supervision
• Logic circuit power monitoring
• Embedded controller reset management

Supervisors Procurement Notes

Verify the exact suffix (e.g., T&R) for packaging configuration, as standard tape-and-reel variants may differ in physical handling requirements. Confirm RoHS compliance status for current production lots, as older Maxim Integrated stock may vary. Ensure the operating voltage aligns with the 4.75V–5.25V specification to avoid improper triggering. Check for obsolescence notices, as this component belongs to a legacy product line that may have limited availability or replacement options.

Supervisors Selection Notes

Select this component when a simple, cost-effective reset solution is required for 5V systems. The fixed 4.13V threshold suits applications where precise programmability is unnecessary. Consider the SOT-23-3 package for space-constrained designs. Evaluate if the manual pushbutton feature meets interface requirements, as it eliminates external button components. Compare against other EconoReset variants if different voltage thresholds or dual-channel capabilities are needed.

Supervisors Part Context

The DS1813-15 belongs to the Maxim Integrated EconoReset series, designed for low-cost voltage supervision. This family simplifies design by integrating reset functionality and manual controls into small packages. The DS1813 variant specifically targets 5V applications, offering a balance between performance and simplicity. It serves as a fundamental building block for ensuring system stability during power transitions in consumer and industrial electronics.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct pin-to-pin replacements such as DS1813-10 or DS1813-5 only if voltage thresholds match application needs. Consult manufacturer datasheets for updated lifecycle status and recommended alternatives before finalizing design changes.

Supervisors FAQ

What is the reset timeout duration for the DS1813-15?

The minimum reset timeout is 100ms, ensuring sufficient time for power supplies to stabilize before asserting the reset signal.

How does the manual reset function work on this IC?

The IC includes an integrated pushbutton input that allows users to manually trigger a reset signal independently of the supply voltage level.

What is the output configuration of the reset signal?

The reset output is open-drain or open-collector, requiring an external pull-up resistor to function correctly with most logic families.
