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 voltage with a threshold of 4.625 V and an overvoltage threshold of 4.75 V. The device features 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 within 5%. The reset delay time is specified at 350 ms, while the quiescent current is 50 uA. It is housed in an SOT-223-4 package for surface mount installation and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides reliable power supervision with integrated power fail detection for system stability.
• Features a compact SOT-223-4 surface mount package suitable for space-constrained designs.
• Delivers low quiescent current consumption to minimize power usage during operation.

Supervisors Applications

• Embedded systems requiring precise voltage monitoring
• Portable electronic devices needing low-power supervision
• Industrial control units utilizing surface mount technology

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status and specific manufacturing lot details prior to integration. Ensure compatibility with existing PCB footprints and thermal management requirements. Review datasheet specifications for operating conditions to validate performance in target environments.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with power fail detection is required. The SOT-223-4 package suits surface-mount applications. Consider the 4.625 V threshold and 350 ms reset delay against system timing needs. Evaluate the 50 uA current draw for battery-operated or energy-efficient designs.

Supervisors Part Context

Part of the DS1833 EconoReset family, designed for cost-effective voltage supervision. Shares functional similarities with other Maxim Integrated supervisors but differs in package and specific electrical thresholds. The Z suffix typically indicates lead-free and RoHS-compliant construction compared to older variants.

Supervisors Replacement Considerations

DS1833Z-5+ serves as a direct equivalent part number variant. Verify pinout compatibility and electrical parameter alignment before substitution. Cross-reference with DS1833-5+ for through-hole alternatives if packaging changes are permissible.
