DS1833-15+

Supervisors Overview

The DS1833-15+ is a voltage supervisory circuit from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It functions as a power-fail monitor with an automatic reset capability. The device features a precision temperature-compensated voltage reference and sensor to maintain system integrity. It provides an active high reset signal that remains asserted for 350ms after power supply recovery. The component operates within a supply voltage range of 2.0V to 5.5V and is housed in a TO-92-3 package.

Supervisors Feature Summary

• Integrates a precision temperature-compensated voltage reference and sensor for accurate monitoring
• Provides automatic reset generation upon power-fail or power-good conditions
• Maintains an active high reset output for a specified duration following power restoration

Supervisors Applications

• Embedded systems requiring reliable power supervision
• Microcontroller-based designs needing automatic reset on brown-out events
• Industrial control circuits operating in varying thermal environments

Supervisors Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm threshold voltage accuracy and package type. Ensure compatibility with existing board layouts using the TO-92-3 through-hole footprint. Confirm RoHS compliance status via the manufacturer's current certification records before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor with an active high output is required. The fixed threshold voltage suits applications where precise monitoring of standard logic rails is necessary. Consider the through-hole mounting style if surface area constraints are not critical. Evaluate the 350ms reset delay against system startup requirements to ensure adequate stabilization time.

Supervisors Part Context

This part belongs to the DS1833 EconoReset family, designed for cost-sensitive applications. It simplifies power management by combining monitoring and reset generation in a single small package. The series is widely used in consumer electronics and industrial equipment where basic power supervision is sufficient without complex configuration options.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the DS1833 series with different threshold suffixes. Verify functional equivalence with other Maxim Integrated supervisors offering similar active high outputs and TO-92-3 packaging.
