DS1833Z-5/T&R

Supervisors Overview

The DS1833Z-5/T&R is a voltage supervisory circuit from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It features a single monitored input with a threshold voltage of 4.625 V and an overvoltage threshold of 4.75 V. The device provides an active low, open drain, push-pull output type and includes power fail detection capabilities. It operates within a supply voltage range up to 5.5 V and maintains accuracy of 5%. The reset delay time is specified at 350 ms, with no manual reset or watchdog timer functionality. Operating temperatures range from -40°C to +85°C.

Supervisors Feature Summary

• Provides voltage supervision with power fail detection for system integrity
• Features non-volatile memory configuration via I2C interface
• Delivers active low, open drain, push-pull output signals

Supervisors Applications

• Embedded systems requiring voltage monitoring
• Portable electronic devices needing power supervision
• Industrial control circuits with single voltage rail oversight

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance details as specified in official documentation. Ensure package type matches SOIC-Narrow-8 requirements for PCB integration. Check manufacturing date codes against project timelines given potential supply constraints. Validate electrical parameters against specific application thresholds before final procurement decisions.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with non-volatile settings is required. Consider the 4.625 V threshold for standard 5V logic systems. Evaluate the 350 ms reset delay against system startup timing needs. Assess the SOIC-Narrow-8 package suitability for space-constrained designs. Verify compatibility with I2C-based configuration methods if persistent settings are necessary across power cycles.

Supervisors Part Context

This part belongs to the DS1833Z series of voltage supervisors, designed for cost-sensitive applications. It integrates EEPROM for storing configuration data, allowing customization without external components. The series targets industries requiring reliable power management in compact form factors. Analog Devices/Maxim Integrated positions these devices as economical solutions for basic reset and monitoring functions.

Supervisors Replacement Considerations

DS1833-5+ serves as a direct pin-compatible alternative within the same product family.
