DS1818R-10/T&R

Supervisors Overview

The DS1818R-10+T&R is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5V with a fixed threshold of 2.88V. The device features an active-low open-drain output and provides a minimum reset timeout of 100ms. Designed for surface-mount applications, it utilizes a SOT-23-3 package and supports an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple power-on reset functionality with a fixed voltage threshold
• Features an active-low open-drain output compatible with various logic families
• Includes a manual reset input capability for system control

Supervisors Applications

• Microprocessor and microcontroller power supply monitoring
• Battery-powered systems requiring low quiescent current
• Embedded systems needing reliable power-up sequencing

Supervisors Procurement Notes

Verify the specific suffix '10' corresponds to the 2.88V threshold requirement for your design. Confirm that the SOT-23-3 package dimensions align with your PCB footprint constraints. Ensure the open-drain output configuration matches the pull-up requirements of your target logic interface. Check for RoHS compliance status if required by your manufacturing standards.

Supervisors Selection Notes

Select this component when a fixed 2.88V supervision level is appropriate for the monitored rail. The open-drain output requires an external pull-up resistor; ensure the value suits the bus capacitance and speed requirements. Consider the 100ms minimum timeout duration to accommodate power ramp-up times in your specific application environment.

Supervisors Part Context

This part belongs to the DS1818 family of supervisory circuits, which are designed for cost-sensitive applications. The 'R' indicates the reel packaging format, while '+T&R' denotes tape and reel delivery. It is distinct from other variants like the DS1818R-20, which offers a different voltage threshold.

Supervisors Replacement Considerations

Direct substitutes include other DS1818 variants with matching thresholds or pin-compatible supervisors from the same manufacturer. Verify that any replacement maintains the same open-drain output type and reset timeout characteristics to ensure circuit compatibility.
