DS1830U+T&R

Supervisors Overview

The DS1830U+T&R is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1 V to 5.5 V and features three monitored inputs with an overvoltage threshold of 4.74 V. The device provides active low, open-drain outputs and includes manual reset functionality with a reset delay time of 20 ms. It does not include a watchdog timer or battery backup switch. Designed for surface mount applications, it is housed in a uSOP-8 package and functions reliably across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides voltage supervision for three distinct monitored inputs
• Features manual reset capability with defined delay timing
• Delivers active low, open-drain output signals

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix T&R indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Ensure the uSOP-8 footprint matches your PCB layout requirements. Check current availability as distribution may be limited. Validate that the 5.5 V maximum rating suits your system voltage.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision. The three-input architecture simplifies designs needing comprehensive power monitoring without additional ICs. The manual reset feature allows for user-initiated recovery actions. Consider the open-drain output compatibility with your logic levels. Verify thermal performance within the specified industrial temperature range.
