DS1233D-10+

Supervisors Overview

The DS1233D-10+ is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It provides power supply monitoring with an open-drain or open-collector output and active-low reset functionality. The device features a minimum reset timeout of 250ms and operates within a temperature range of -40°C to 85°C. It utilizes a TO-92-3 through-hole package and monitors a single voltage input with a threshold of 4.375V.

Supervisors Feature Summary

• Provides simple reset and power-on reset functions for microprocessor systems
• Features open-drain or open-collector output configuration
• Includes manual reset capability for external override

Supervisors Applications

• Microprocessor system supervision
• Power-on reset generation
• Manual reset circuit implementation

Supervisors Procurement Notes

Verify the specific manufacturer part number DS1233D-10+ against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the TO-92-3 package matches the target PCB footprint requirements. Confirm that the 4.375V threshold aligns with the monitored rail voltage. Check for any lead time variations due to high order volumes as noted by distributors.

Supervisors Selection Notes

Select this component when a low-cost, single-channel supervisor with a fixed 4.375V threshold is required. The TO-92-3 package suits through-hole designs where space is not critical. Consider the 250ms minimum reset timeout for system stability requirements. Verify that the active-low reset polarity matches the receiving logic interface.

Supervisors Part Context

This component belongs to the Maxim Integrated EconoReset family, designed for cost-sensitive applications requiring basic power management supervision. The DS1233 variant specifically offers a fixed threshold without programmability, distinguishing it from higher-end models in the lineup that may include watchdog timers or battery backup switches.

Supervisors Replacement Considerations

Direct substitutes within the same series include DS1233A-10+ (different threshold) or other DS1233 variants with compatible packages. Verify threshold voltage differences before substitution.
