DS1233A-15

Supervisors Overview

The DS1233A-15 is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc. (formerly Maxim Integrated). It monitors supply voltages ranging from 1.1V to 5V and features a fixed reset threshold of 2.88V. The device provides a low-active reset signal with a minimum timeout of 250ms. It utilizes an open-drain or open-collector output interface and is housed in a TO-92-3 through-hole package. The component operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides power system supervision for voltages between 1.1V and 5V
• Features a fixed factory-set reset threshold at 2.88V
• Generates a low-active reset signal with a minimum 250ms timeout

Supervisors Applications

• Embedded systems requiring reliable power-on reset sequences
• Microcontroller-based designs needing brown-out protection
• Industrial control circuits operating in wide temperature environments

Supervisors Procurement Notes

Verify the specific suffix designation when ordering, as it indicates the reset threshold voltage. Confirm the package type matches the required PCB footprint, typically TO-92-3 for this series. Ensure the manufacturer source is authorized to guarantee authenticity, given the historical transition from Maxim Integrated to Analog Devices. Check current availability status as distribution may vary.

Supervisors Selection Notes

Select this component when a fixed threshold near 3V is required for 3.3V logic systems. The open-drain output allows flexibility in interfacing with various logic families. Consider the thermal operating range if the application involves extreme environmental conditions. Verify that the 250ms minimum timeout meets the startup requirements of the connected microprocessor or memory devices.

Supervisors Part Context

This part belongs to the EconoReset family, designed for cost-sensitive applications requiring basic power monitoring. The DS1233A variant specifically denotes the 2.88V threshold version. Analog Devices continues support for legacy Maxim products, ensuring long-term availability for established industrial and consumer electronics designs.

Supervisors Replacement Considerations

Compatible substitutes include other parts from the DS1233 series with matching thresholds, such as the DS1233A-10+ which shares the same functional characteristics and package configuration.
