DS1830AU+

Supervisors Overview

The DS1830AU+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors three independent supply voltages and provides reset signals when thresholds are exceeded. The device features an active low, open-drain output and supports manual reset functionality via a pushbutton input. It operates within a supply voltage range of 1 V to 5.5 V and includes power-fail detection capabilities. The component is housed in an 8-pin uSOP package and is designed for through-hole or surface-mount installation depending on the specific variant configuration.

Supervisors Feature Summary

• Monitors three independent voltage rails simultaneously
• Provides active low open-drain reset outputs
• Supports manual reset via external pushbutton
• Includes power-fail detection logic

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset generation
• Industrial control voltage monitoring

Supervisors Procurement Notes

Verify exact package type and threshold specifications against official datasheets before procurement. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure compatibility with existing board layout constraints for the uSOP-8 footprint. Cross-reference manufacturer part numbers to avoid confusion with similar series variants.

Supervisors Selection Notes

Select this component when multi-rail supervision is required without watchdog timer complexity. Consider the open-drain output requirement for pull-up resistor implementation. Evaluate operating temperature range requirements against industrial standards. Verify manual reset integration into the system design for user intervention capabilities.

Supervisors Part Context
