DS1819CR-10+T&R

Supervisors Overview

The DS1819CR-10+T&R is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for monitoring power supply voltages. It operates within a supply voltage range of 2.7V to 5.5V and features a reset threshold voltage of 4.35V. The device provides a push-pull output configuration with active high and active low capabilities. It includes a fixed reset delay time of 200ms and maintains an accuracy of 2.5%. The component supports a maximum operating temperature of +85°C and a minimum of -40°C, housed in an SOT-23-5 package.

Supervisors Feature Summary

• Provides simultaneous monitoring for both 5V and 3.3V microprocessor systems
• Features integrated watchdog timer functionality for system reliability
• Includes manual reset input capability for user-initiated control

Supervisors Applications

• Microprocessor power supply supervision
• Embedded system reset management
• Industrial control board monitoring

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the ordering information matches the exact thermal grade and package variant required for your design. Cross-reference the datasheet revision history to validate parameter consistency before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when dual-voltage monitoring for 5V and 3.3V rails is required within a single channel. Consider the 200ms reset delay and 2.5% accuracy specifications against system timing requirements. Evaluate the SOT-23-5 package constraints against available PCB real estate and thermal dissipation needs for the target application environment.

Supervisors Part Context

This part belongs to the DS1819 MicroMonitor series from Maxim Integrated, now part of Analog Devices. The series focuses on compact supervisory solutions for embedded applications. The CR designation typically indicates a specific thermal or packaging variant within the broader product family, distinguishing it from other suffixes like AR or ER.

Supervisors Replacement Considerations

Consult official cross-reference lists for verified substitutes such as the DS1819AR-10+T&R. Verify that any alternative maintains identical threshold voltages and package dimensions to ensure direct compatibility without redesigning the host circuit board.
