DS1816-10+T

Supervisors Overview

The DS1816-10+T is a supervisory circuit manufactured by Analog Devices Inc. (formerly Maxim Integrated). It functions as a voltage monitor designed to maintain a microprocessor in reset during power transients and automatically restart it upon power restoration. The device features an open-drain output with an internal pull-up resistor, eliminating the need for external components. It provides accurate power supply monitoring with a specified tolerance of 10%, making it suitable for systems requiring reliable supervision.

Supervisors Feature Summary

• Automatically restarts a microprocessor after a power failure event
• Maintains reset signal for approximately 150ms after VCC returns to an in-tolerance condition
• Utilizes precision temperature-compensated voltage reference and sensor for accurate monitoring
• Features efficient open-drain output with an internal 5k pull-up resistor

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring in embedded systems
• Battery-operated handheld applications
• Low-cost electronic designs requiring discrete component reduction

Supervisors Procurement Notes

Verify the specific suffix designation against official datasheets, as variations such as +T&R or /T&R may indicate tape-and-reel packaging which differs from standard tube packaging. Confirm that the '10' suffix corresponds to the required 10% threshold voltage accuracy for your application. Ensure compatibility with the target operating temperature range of -40°C to +85°C before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a low-cost solution for maintaining processor reset during power anomalies is required. It is appropriate for designs utilizing 3V systems where 20% tolerance is acceptable, though the '10' variant targets 10% accuracy. Consider the SOT-23 package for space-constrained PCB layouts. Verify that the open-drain output configuration aligns with the logic levels of the connected microprocessor reset pin.

Supervisors Part Context

This part belongs to the EconoReset family of supervisory circuits from Maxim Integrated. These devices are engineered to replace multiple discrete components typically used for power management. The series includes variants with different output types and voltage thresholds, providing flexible options for various microcontroller architectures and power supply requirements.

Supervisors Replacement Considerations

Check for direct equivalents within the DS1816 series, such as the DS1816R-10+, ensuring identical voltage thresholds and package types. Cross-reference with other EconoReset models if pinout compatibility allows.
