DS1815-5

Supervisors Overview

The DS1815-5 is a supervisory circuit from the EconoReset series manufactured by Analog Devices Inc./Maxim Integrated. It functions as a voltage monitor with a single monitored input and an active low, push-pull output. The device provides a reset signal upon power failure detection, featuring a minimum reset delay time of 150 ms. It operates within a supply voltage range of up to 5.5 V and supports through-hole installation in a TO-92-3 package. The component is rated for an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates power-fail detection capability for monitoring supply voltage integrity
• Features an active low push-pull output stage for direct logic interfacing
• Provides a defined reset timeout period to ensure stable system initialization

Supervisors Applications

• Microprocessor system supervision
• Power management circuits requiring voltage monitoring
• Embedded systems needing reliable reset generation

Supervisors Procurement Notes

Verify current availability status as the product may be subject to limited supply or discontinuation notices. Confirm that the specific package type and electrical specifications match the design requirements before ordering. Check for any RoHS compliance documentation updates relevant to the manufacturing date code.

Supervisors Selection Notes

Select this component when a simple, cost-effective voltage supervisor with a fixed threshold is required. Ensure the application does not need manual reset functionality or watchdog timer features, as these are absent in this model. Verify that the through-hole TO-92-3 package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the EconoReset series, designed for basic voltage monitoring applications. It serves as a fundamental building block for ensuring system reliability by detecting under-voltage conditions. The series typically offers a balance between performance and simplicity for standard digital logic supplies.
