DS1817R-10-U+

Supervisors Overview

The DS1817R-10-U+ is a supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It provides reset functionality for microprocessors and digital systems with a fixed output delay of 100 ms. The device monitors the supply voltage and asserts a reset signal when the voltage drops below a specific threshold. It operates within a supply voltage range of 2.0 V to 5.5 V. The component features an open-drain or push-pull active-low reset output, ensuring reliable system recovery from power failures.

Supervisors Feature Summary

• Provides precise voltage monitoring for system stability
• Includes a fixed internal delay timer for stable reset assertion
• Offers low-power operation suitable for battery-driven applications

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Portable electronic devices requiring power supervision
• Industrial control systems needing voltage monitoring

Supervisors Procurement Notes

Verify the exact suffix 'U+' indicates the lead-free and RoHS compliant version. Confirm the package type matches your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the manufacturer's latest datasheet for any pinout revisions or updated electrical characteristics before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 100 ms reset delay is required. Consider the input voltage range compatibility with your system's power rail. Evaluate the current consumption against battery life requirements. Verify that the output drive capability meets the load connected to the reset line. Check if the open-drain configuration suits your pull-up resistor design.

Supervisors Part Context

This part belongs to the Maxim Integrated supervisory circuit family. These components are designed to monitor power supplies and generate reset signals for digital logic. The DS1817 series typically includes variants with different delay times and thresholds. This specific model focuses on standard voltage monitoring with a fixed timing characteristic.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the same manufacturer's portfolio. Verify equivalent delay times and threshold voltages. Ensure compatible package types and thermal performance. Review alternative suppliers for similar supervisory ICs with matching electrical specifications.
