DS1831CS+

Supervisors Overview

The DS1831CS+ is a multi-supply voltage monitor from the MicroMonitor series, housed in a 16-SOIC package. It monitors two input voltages with fixed thresholds of 3.3 V and 5 V. The device features an active low, open-drain reset output and supports manual reset functionality. It operates within a supply voltage range up to 5.5 V and includes power-fail detection capabilities. The component maintains accuracy within 2.5% and draws a typical operating current between 85 uA and 100 uA.

Supervisors Feature Summary

• Monitors multiple power supplies simultaneously using fixed threshold levels for system integrity.
• Provides active low open-drain reset signals compatible with standard digital logic interfaces.
• Includes manual reset input capability for controlled system initialization or recovery.

Supervisors Applications

• Multi-voltage embedded systems requiring simultaneous power rail supervision
• Industrial control units needing power-fail warning detection
• Consumer electronics utilizing 3.3V and 5V dual-rail architectures

Supervisors Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm exact threshold configurations and package variations. Confirm RoHS compliance status and lead times through authorized distributors, as availability may vary by region. Ensure the selected variant matches the required operating temperature range and electrical specifications for the target application environment.

Supervisors Selection Notes

Select this component when fixed 3.3 V and 5 V monitoring thresholds are sufficient for the design requirements. Consider the open-drain output configuration for compatibility with pull-up resistor networks. Evaluate the 2.5% accuracy specification against system tolerance needs. Verify that the 16-SOIC package dimensions fit the PCB layout constraints and thermal management requirements.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroMonitor family, designed for supervising complex power systems. It integrates voltage monitoring and reset generation into a single compact solution. The series typically offers configurable delays and thresholds in other variants, but this specific model provides fixed thresholds for simplified implementation in standard voltage environments.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the DS1831 family or newer Analog Devices supervisory ICs. Verify that replacement parts maintain the same 3.3 V and 5 V threshold values and open-drain output characteristics. Ensure any substitute supports the same 16-SOIC package and operating temperature range.
