DS1233M-3

Supervisors Overview

The DS1233M-3 is a single-channel voltage supervisor IC from the EconoReset series. It monitors input voltages and generates an active-low reset signal when the supply drops below the threshold of 2.72V. The device features a minimum reset timeout of 200ms and operates within a temperature range of -40°C to +85°C. It utilizes an open-drain or open-collector output configuration.

Supervisors Feature Summary

• Provides reliable power system supervision for microprocessors and digital controllers
• Generates active-low reset signals upon undervoltage detection
• Ensures stable operation with defined reset timeout periods

Supervisors Applications

• Microprocessor power management systems
• Digital controller circuit protection
• Embedded system voltage monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to obsolescence status. Confirm package type TO-92-3 and pinout compatibility during integration. Check datasheet revisions for updated electrical characteristics and handling instructions prior to deployment in production environments.

Supervisors Selection Notes

Select this component for applications requiring simple, low-cost voltage supervision. Ensure the 2.72V threshold aligns with target logic levels. Verify that the open-drain output suits the downstream interface requirements without additional pull-up components.

Supervisors Part Context

Part of the Maxim Integrated EconoReset family designed for cost-sensitive embedded designs. Replaced by newer generations but remains documented for legacy system maintenance and specific industrial replacements.

Supervisors Replacement Considerations

DS1233M-3+ is the RoHS-compliant equivalent. Cross-reference with DS1233A variants for different thresholds or packages.
