DS1830AS+T&R

Supervisors Overview

The DS1830AS+T&R is a voltage sequencer and supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features two monitored inputs with a threshold voltage of 3.3 V and an overvoltage threshold of 3.15 V. The device provides active low, open-drain outputs and includes manual reset functionality without a watchdog timer or battery backup switch. It operates within a supply voltage range up to 5.5 V and consumes 25 uA of working power. Accuracy is rated at 20%, with a reset delay time of 75 ms. The component supports surface mount installation in an SOIC-8 package and functions reliably between -40°C and +85°C.

Supervisors Feature Summary

• Monitors multiple power rails using dedicated input channels for system stability
• Provides manual reset capability for controlled system restarts
• Generates active low open-drain signals for microprocessor interfacing

Supervisors Applications

• Embedded systems requiring multi-voltage supervision
• Industrial control units needing manual reset interfaces
• Consumer electronics utilizing standard logic levels

Supervisors Procurement Notes

Verify the specific suffix designation against official datasheets to confirm pinout and electrical characteristics match design requirements. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure the SOIC-8 package dimensions align with PCB footprint specifications. Validate operating temperature ranges against environmental constraints of the final assembly.

Supervisors Selection Notes

Select this component when dual-channel voltage monitoring with manual reset is required. Consider the 20% accuracy rating and 75 ms delay for timing-sensitive applications. Evaluate the open-drain output structure for compatibility with downstream logic levels. Compare power consumption figures against battery-operated constraints if applicable.
