DS1830

Supervisors Overview

The DS1830 is a voltage supervisory circuit designed for monitoring power supply integrity. It features a manual reset input and an active low open-drain output. The device operates within a supply voltage range of 1V to 5.5V with a typical quiescent current of 10uA. It provides a fixed threshold voltage of 3.3V and includes a reset delay time of 15ms. The component supports through-hole installation in an 8-PDIP package and functions across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Manual reset capability via pushbutton interface
• Active low open-drain reset output signal
• Integrated power-fail detection functionality

Supervisors Applications

• Embedded system power supply supervision
• Microcontroller reset sequence generation
• Voltage level monitoring in portable electronics

Supervisors Procurement Notes

Verify the specific suffix designation, as variants such as DS1830A+ differ in pin count and channel configuration from the base model. Confirm RoHS compliance status and lead times with authorized distributors, noting that several versions are marked as obsolete or end-of-life. Ensure the selected package matches the target PCB footprint requirements before ordering.

Supervisors Selection Notes

Select this component when a single-channel supervisor with manual reset is required. Compare against the DS1830AS for surface-mount needs or the DS1830A for three-channel monitoring. Verify that the 3.3V threshold aligns with the monitored rail voltage. Check if additional watchdog timer functionality is needed, which requires alternative part numbers like the DS1831 series.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroMonitor family of supervisory circuits. It serves as a fundamental building block for ensuring reliable system startup and operation by detecting under-voltage conditions. The series offers various configurations including multi-channel monitors and sequencers to address complex power management requirements in industrial and consumer applications.
