DS1830+

Supervisors Overview

The DS1830+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors three independent input voltages and provides active-low open-drain reset outputs when thresholds are exceeded. The device supports manual reset functionality via an external pushbutton. Key electrical parameters include a maximum supply voltage of 5.5 V, a typical operating current of 10 uA, and a reset delay time of 15 ms. It operates within a temperature range of -40°C to +85°C and is available in an 8-pin PDIP package.

Supervisors Feature Summary

• Monitors three independent voltage inputs for power system integrity
• Provides active-low open-drain reset signals upon threshold violation
• Supports manual reset control through an external pushbutton interface

Supervisors Applications

• Embedded systems requiring multi-voltage supervision
• Industrial control units with multiple power rails
• Communication equipment needing reliable power monitoring

Supervisors Procurement Notes

Verify the specific suffix (e.g., A, U) as it determines the monitored voltage thresholds and package type. Confirm availability status, as some variants may be discontinued or have limited stock. Ensure the selected version matches the required input voltage levels and thermal operating range for your design.

Supervisors Selection Notes

Select based on the specific voltage thresholds required for each monitored rail. Consider the package style (PDIP vs. uSOP) for board layout constraints. Verify that the manual reset feature aligns with system safety requirements. Check if the standard 15 ms delay meets the timing specifications of the downstream logic components.

Supervisors Part Context

This component belongs to the DS1830 series of micromonitor circuits designed for supervising multiple power supplies. It is part of Maxim Integrated's portfolio of power management ICs focused on system reliability. The series offers various configurations to accommodate different voltage levels and package preferences for diverse electronic applications.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the DS1830 family with adjusted suffixes for different voltage thresholds. Verify functional equivalence regarding reset delay and output configuration before substitution.
