DS1816-5+

Supervisors Overview

The DS1816-5+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5 V to 5.5 V and features a threshold voltage of 4.62 V. The device provides an active low, open-drain reset output with a minimum reset delay time of 150 ms. It supports power failure detection without manual reset or watchdog timer functions. The component is housed in a TO-92-3 package and is designed for through-hole installation.

Supervisors Feature Summary

• Monitors power supply status using a precision temperature-compensated voltage reference
• Generates internal power-fail signal when out-of-tolerance conditions are detected
• Maintains reset state for approximately 150ms after supply returns to tolerance

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring circuits
• Automatically restarting systems after power failure

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Confirm availability status as distribution channels may list limited stock or obsolete inventory. Ensure the selected variant matches the required threshold voltage and output configuration for the target application design.

Supervisors Selection Notes

Select this component for applications requiring simple, cost-effective power supply supervision with an open-drain output interface. Consider the TO-92-3 package constraints for through-hole mounting requirements. Evaluate the fixed threshold voltage against the specific system power rail tolerances to ensure reliable reset generation during brown-out events.

Supervisors Part Context

This part belongs to the EconoReset series of supervisory circuits from Maxim Integrated. It is designed to replace discrete components in microprocessor reset circuits. The series offers various threshold voltages and output configurations to accommodate different system power requirements and interface needs.
