DS1816R-10-U+

Supervisors Overview

The DS1816R-10-U+ is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It monitors one input voltage with a threshold of 3.06V and provides an active-low reset signal via an open-drain or open-collector output. The device features a minimum reset timeout of 100ms and operates within a supply voltage range of 1V to 5.5V. It is housed in a SOT-23-3 package, suitable for surface-mount installation, and supports a working temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset or power-on reset functionality for monitored circuits
• Features an open-drain or open-collector output compatible with various logic families
• Includes a manual reset input capability for system control

Supervisors Applications

• Microprocessor system supervision
• Battery-powered equipment monitoring
• Portable instrumentation power management

Supervisors Procurement Notes

Verify the specific suffix 'U+' indicates the lead-free RoHS-compliant variant when ordering. Confirm the package type matches the required PCB footprint, as the standard designation refers to the SOT-23-3 form factor. Ensure the supplier source aligns with authorized distribution channels to guarantee component authenticity and traceability for critical applications.

Supervisors Selection Notes

Select this component when a low-cost, single-channel supervisor with a fixed threshold near 3.06V is required. It is appropriate for designs needing an active-low reset signal with open-drain output flexibility. Consider the 100ms minimum timeout and operating temperature range to ensure compatibility with the target system's power-up sequence and environmental conditions.

Supervisors Part Context

This part belongs to the DS1816 family of supervisory circuits, designed for cost-sensitive applications requiring basic voltage monitoring. The EconoReset series focuses on providing essential reset functions without complex programmability. The 'R' suffix typically denotes the reel packaging format, while 'U' specifies the SOT-23-3 package style within the manufacturer's nomenclature.

Supervisors Replacement Considerations

Direct substitutes include other DS1816 variants with different thresholds, such as the DS1816R-5+T&R (3.06V) or DS1816R-10-U+ (3.08V). Cross-referencing with similar open-drain supervisors from other manufacturers requires verifying pinout compatibility and electrical parameter alignment.
