DS1833Z-5+

Supervisors Overview

The DS1833Z-5+ is a voltage supervisory circuit from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single input channel with a threshold voltage of 4.625 V and an overvoltage threshold of 4.75 V. The device features a reset delay time of 250 ms minimum and operates within a supply voltage range of 2.7 V to 5.5 V. It provides a high-active push-pull output and functions reliably across a temperature range of -40°C to +85°C. The component is housed in a SOT-223-3 package.

Supervisors Feature Summary

• Provides power-fail detection for system supervision
• Features a high-active push-pull output driver
• Includes manual reset capability for user control

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix designation (+) against the manufacturer's current documentation to confirm RoHS compliance status. Confirm availability through authorized channels as distribution status may vary. Ensure the SOT-223-3 package matches the target PCB footprint requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor with manual reset functionality is required. The push-pull output allows direct interfacing with logic inputs without external pull-ups. Consider the 4.625 V threshold for standard 5V systems. Verify that the SOT-223-3 package is suitable for the assembly process.

Supervisors Part Context

This part belongs to the DS1833 family of voltage supervisors. It shares functional similarities with other EconoReset devices but is distinguished by its specific threshold voltage and package type. The family is designed for cost-sensitive applications requiring basic power monitoring and reset generation capabilities.

Supervisors Replacement Considerations

Check for DS1833 variants with different suffixes or packages. Verify pin compatibility and electrical specifications before substitution.
