DS1810R-5+T&R

Supervisors Overview

The DS1810R-5+T&R is a supervisory circuit from the EconoReset family, manufactured by Analog Devices Inc. (Maxim Integrated). It features a single voltage monitor channel with an active low push-pull output. The device monitors input voltages up to a maximum of 5.5 V and triggers a reset when the threshold drops below 4.62 V. It includes a minimum reset timeout of 100 ms and operates within a temperature range of -40°C to +85°C. The component is housed in a SOT-23-3 surface-mount package.

Supervisors Feature Summary

• Provides automatic power-on reset functionality for digital systems
• Features a push-pull output stage for direct logic interfacing
• Includes a fixed reset delay timer to ensure stable power-up sequences

Supervisors Applications

• Microcontroller power supply supervision
• Embedded system voltage monitoring
• Portable electronic device protection

Supervisors Procurement Notes

Verify the specific suffix designation against the manufacturer's current product status documentation. Confirm that the 'R' indicates the reel packaging format and the '+T&R' specifies the tape and reel quantity. Ensure compatibility with the required 5V logic levels and check for any obsolescence notices or lifecycle changes before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a simple, cost-effective solution for voltage monitoring is required without manual reset capabilities. It is suitable for applications where a fixed 100 ms delay is acceptable for system initialization. Consider alternative packages if space constraints differ from the SOT-23-3 footprint requirements.

Supervisors Part Context

This part belongs to the DS1810 series of supervisory circuits designed for low-cost, high-reliability applications. It serves as a fundamental building block for ensuring system stability during power transitions. The series is widely used in consumer electronics and industrial control modules where basic voltage supervision is critical for preventing erratic microcontroller behavior.

Supervisors Replacement Considerations

Consult official cross-reference guides for compatible parts with identical pinouts and electrical characteristics. Verify that substitute components maintain the same 4.62 V threshold and push-pull output configuration to ensure seamless integration without circuit redesign.
