DS1833-5

Supervisors Overview

The DS1833-5 is a voltage supervisory circuit from the EconoReset series by Analog Devices Inc./Maxim Integrated. It monitors a single input channel with a threshold voltage of 4.625 V and an overvoltage threshold of 4.74 V. The device features an active high, open drain output type with a reset delay time of 350 ms. Operating within a supply voltage range up to 5.5 V, it consumes 50 uA of working power current. The component supports through-hole installation in a TO-92-3 package and functions reliably across a temperature range of -40 C to +85 C.

Supervisors Feature Summary

• Provides simple reset or power-on reset functionality for monitored voltage rails
• Features an active high output configuration suitable for direct logic interfacing
• Designed for low-power applications with minimal quiescent current consumption

Supervisors Applications

• Monitoring microprocessor supply voltages
• Ensuring system stability during power-up sequences
• Protecting circuits from undervoltage conditions

Supervisors Procurement Notes

Verify component authenticity due to end-of-life status. Confirm RoHS compliance requirements as documentation indicates non-compliance for some variants. Check specific manufacturing date codes against project timelines. Ensure TO-92-3 through-hole mounting compatibility with existing PCB layouts. Validate supplier authorization for discontinued stock.

Supervisors Selection Notes

Select this component when a fixed 4.625 V threshold is required for single-channel monitoring. Consider the TO-92-3 package constraints for space-limited through-hole designs. Evaluate the 350 ms reset delay against system startup timing requirements. Assess the 50 uA current draw impact on overall battery life or power budget.
