DS1834AS

Supervisors Overview

The DS1834AS is a dual-channel voltage supervisor from the MicroMonitor family, designed for dual-voltage systems. It monitors two independent supply voltages and asserts an active-low open-drain reset signal when either input falls below its threshold. Key electrical parameters include a maximum supply voltage of 5.5 V, a reset delay time of 350 ms, and a typical operating current of 50 uA. The device features manual pushbutton reset capability and operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors two independent power supply rails simultaneously
• Includes manual pushbutton reset functionality
• Provides active-low open-drain reset output

Supervisors Applications

• Dual-voltage embedded processing systems
• Microcontroller power supervision
• Portable electronic devices requiring low standby current

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance details as specifications may vary by manufacturing date. Check for alternative package options if surface-mount availability is limited. Ensure design-in compatibility with existing voltage thresholds before procurement.

Supervisors Selection Notes

Select this component for applications requiring simultaneous monitoring of two distinct voltage rails. The integrated pushbutton feature simplifies user interface design without external components. Consider the 50 uA quiescent current for battery-operated designs. Verify that the open-drain output aligns with the target system's logic level requirements.

Supervisors Part Context

Part of the Maxim Integrated MicroMonitor series, the DS1834AS belongs to the EconoReset line focused on cost-effective supervision. It complements single-channel variants like the DS1826 and multi-channel models such as the DS1831. The SOIC-8 package offers a compact solution for space-constrained PCB layouts compared to larger DIP packages.
