DS1233D-15+T&R

Supervisors Overview

The DS1233D-15+T&R 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 1.2V to 5.5V and features a fixed reset threshold of 4.125V. The device provides an active-low open-drain or open-collector output with a minimum reset timeout of 250ms. Designed for surface-mount applications, it utilizes a SOT-223-3 package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors a single power supply rail with a fixed threshold voltage
• Generates a system reset signal upon power failure detection
• Provides manual pushbutton reset capability

Supervisors Applications

• Microprocessor system supervision
• Power management circuit monitoring
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tolerance. Confirm RoHS compliance status through manufacturer datasheets. Ensure the ordering part number matches the required tape and reel quantity specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.125V threshold is required for systems operating up to 5.5V. The SOT-223-3 package suits space-constrained surface-mount designs. Consider the 250ms minimum timeout for applications requiring extended stabilization periods. Verify that the open-drain output configuration aligns with the target logic interface requirements.

Supervisors Part Context

This component belongs to the DS1233 family of voltage supervisors designed for cost-sensitive applications. The EconoReset series offers basic reset functionality without additional features like watchdog timers or battery backup switching. It serves as a fundamental protection element in digital circuits requiring reliable power-on reset sequences.

Supervisors Replacement Considerations

Consult official substitution guides for pin-compatible alternatives within the same product family. Verify electrical parameter compatibility including threshold voltage and output drive capabilities before replacing.
