DS1830U+

Supervisors Overview

The DS1830U+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for monitoring power supply integrity. It features a single monitored input with a threshold voltage of 5 V and supports a maximum supply voltage of 5.5 V. The device operates within a temperature range of -40°C to +85°C and consumes a typical quiescent current of 35 uA. It provides an active low, open-drain output with a reset delay time of 20 ms and includes manual reset functionality via a pushbutton interface.

Supervisors Feature Summary

• Integrates manual reset capability through a dedicated pushbutton interface for user-initiated system recovery.
• Detects power failure events to ensure reliable supervision of critical voltage levels during operation.
• Delivers an active low, open-drain output signal compatible with standard digital logic interfaces.

Supervisors Applications

• Embedded systems requiring supervised power rails with manual intervention capabilities
• Industrial control units needing robust voltage monitoring in harsh thermal environments
• Consumer electronics utilizing single-input voltage supervision architectures

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm package variant matches the uSOP-8 specification required for surface-mount assembly. Validate RoHS compliance documentation against current regulatory standards before integration into final products.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with manual reset is required. Ensure the 5 V threshold aligns with the target supply rail. Consider the open-drain output configuration for compatibility with downstream logic circuits. Verify that the 20 ms reset delay meets system timing requirements.

Supervisors Part Context

This part belongs to the DS1830U series of supervisory circuits from Maxim Integrated. It serves as a specialized solution for applications demanding precise voltage monitoring combined with user-controlled reset mechanisms. The device complements other PMIC offerings by providing focused power management functionality.

Supervisors Replacement Considerations

DS1830A+ offers similar supervisory functions but utilizes a PDIP-8 through-hole package instead of surface-mount. Both parts share comparable electrical characteristics and manual reset features, though package selection dictates board layout compatibility.
