DS1813R-10+T&R

Supervisors Overview

The DS1813R-10+T&R is a voltage monitor from the EconoReset series by Analog Devices Inc./Maxim Integrated. It features a single monitored input with an open-drain output and active-low reset signal. The device has a threshold voltage of 4.13 V, a reset delay time of 150 ms, and operates within a supply voltage range up to 5.5 V. It provides power failure detection and maintains accuracy within 2.5%. The component functions in temperatures ranging from -40°C to +85°C and is housed in a SOT-23-3 package.

Supervisors Feature Summary

• Provides simple reset or power-on-reset functionality for single-channel monitoring
• Features an open-drain output compatible with various logic families
• Includes power failure detection capability for system protection

Supervisors Applications

• Microprocessor system supervision
• Portable equipment power management
• Battery-operated device monitoring

Supervisors Procurement Notes

Verify the specific suffix 'R-10' corresponds to the 4.13 V threshold variant when sourcing. Confirm the '+T&R' designation indicates tape-and-reel packaging suitable for automated assembly. Ensure compatibility with the target operating temperature range of -40°C to +85°C. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm current production status and RoHS compliance details before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a low-cost supervisor with an open-drain output is required. The 4.13 V threshold suits 5 V systems requiring precise monitoring. Consider the 150 ms reset delay for application timing requirements. The SOT-23-3 package offers space-efficient surface-mount integration. Verify that the active-low reset polarity aligns with the connected microcontroller or logic interface specifications.

Supervisors Part Context

This part belongs to the DS1813 series of voltage supervisors designed for cost-sensitive applications. It shares the EconoReset family characteristics, focusing on essential monitoring functions without complex interfaces. The series typically includes variants with different thresholds and output types to accommodate diverse system voltage levels and logic requirements across consumer and industrial electronics.

Supervisors Replacement Considerations

Check for direct substitutes within the DS1813 series offering identical 4.13 V thresholds and open-drain outputs. Verify pinout compatibility with the SOT-23-3 footprint. Ensure replacement parts maintain the same reset delay and accuracy specifications to preserve system reliability.
