DS1833Z-15+

Supervisors Overview

The DS1833Z-15+ is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.0 V to 6.0 V and features a fixed threshold voltage of 4.625 V. The device provides a push-pull/totem pole output with an active-high reset signal. It includes a minimum reset timeout of 250 ms to ensure stable power-up sequencing. Designed for surface-mount applications, it is housed in a SOT-223-3 package and supports an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset or power-on reset functionality with a fixed threshold voltage.
• Features a push-pull/totem pole output configuration for direct logic interfacing.
• Includes a guaranteed minimum reset timeout period to prevent premature system activation.

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Microprocessor systems needing reliable power-on reset sequences
• Automotive electronics operating within extended temperature ranges

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Confirm RoHS compliance details as historical data may vary. Check for alternative packages if lead availability is critical. Ensure design-in compatibility with existing PCB footprints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 4.625 V threshold is required for system supervision. The SOT-223-3 package suits space-constrained surface-mount designs. Consider the active-high output polarity against microcontroller input requirements. Evaluate the 250 ms reset delay against system startup timing constraints.

Supervisors Part Context

Part of the EconoReset family designed for cost-sensitive applications. Replaces older TO-92 variants like DS1833-5 with modern surface-mount packaging. Maintains functional compatibility while improving assembly efficiency. Part status is listed as obsolete by the manufacturer.

Supervisors Replacement Considerations

DS1833Z-5+ offers a different threshold voltage (2.93 V). DS1833Z-10+ provides a 4.38 V threshold. Verify exact threshold requirements before substituting. No direct pin-compatible alternatives with identical thresholds are publicly confirmed.
