DS1833-15+T&R/STR

Supervisors Overview

The DS1833-15+T&R/STR is a power-fail monitor and reset circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It belongs to the EconoReset series and features a precision temperature-compensated voltage reference and sensor. The device maintains an active high reset signal for a minimum timeout of 250ms after power failure. It monitors a single channel with a threshold voltage of 4.125V. The component supports through-hole installation in TO-92-3 or TO-226-3 packages and operates within a temperature range of -40°C to 85°C.

Supervisors Feature Summary

• Provides automatic reset functionality upon detection of power-fail conditions
• Integrates a precision temperature-compensated voltage reference and sensor
• Maintains an active high reset output for a specified duration following power interruption

Supervisors Applications

• Microprocessor system supervision
• Power-fail detection circuits
• Brown-out protection systems

Supervisors Procurement Notes

Verify the specific suffix configuration when sourcing, as variations exist between tape-and-reel and strip formats. Confirm RoHS compliance status, noting that some legacy listings may indicate non-compliance. Check current availability as the component may be subject to limited supply or end-of-life restrictions depending on the distributor channel.

Supervisors Selection Notes

Select this component for applications requiring a simple, cost-effective reset solution with a fixed threshold. Ensure the required reset timeout meets the 250ms minimum specification. Verify package compatibility with the target PCB layout, choosing between TO-92-3 or TO-226-3 form factors based on mechanical constraints.

Supervisors Part Context

This part is part of the DS1833 family of voltage supervisors. It shares functional similarities with other EconoReset devices but is distinguished by its specific threshold voltage and package options. It serves as a fundamental building block for ensuring reliable system startup and recovery in embedded electronics.
