DS1834S/T&R

Supervisors Overview

The DS1834S/T&R is a dual-channel voltage monitor and reset controller manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates at a nominal supply voltage of 5 V with a maximum rating of 5.5 V. The device monitors two independent input channels, featuring threshold voltages of 3.3 V and 5 V. It draws a typical operating current of 50 uA and provides an active-low, open-drain output. The component includes a manual reset capability and exhibits a reset delay time of 350 ms. Accuracy is specified at 2.5 percent.

Supervisors Feature Summary

• Dual-channel voltage monitoring with distinct threshold levels for 3.3 V and 5 V inputs
• Active-low open-drain reset output with configurable manual reset functionality
• Low power consumption suitable for battery-operated systems
• Integrated pushbutton reset mechanism for system control

Supervisors Applications

• Monitoring critical voltage rails in embedded systems
• Power supply supervision in industrial control units
• Reset generation for microcontrollers requiring stable power sequencing
• Battery backup system supervision

Supervisors Procurement Notes

Verify availability status carefully as this part may be subject to limited supply or end-of-life conditions. Confirm the exact suffix matches the required package and temperature range. Check for RoHS compliance documentation. Ensure the distributor source is authorized to guarantee component authenticity. Review lead times due to potential manufacturing constraints.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required within a single package. The fixed thresholds simplify design for standard 3.3 V and 5 V logic families. Consider the low quiescent current for energy-efficient applications. Verify that the open-drain output interface aligns with the target system's reset input requirements.
