DS1812R-5-U

Supervisors Overview

The DS1812R-5-U is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It monitors one input voltage with a threshold of 4.62V and provides an active high push-pull output. The device features a reset timeout of 100ms minimum and operates within a temperature range of -40°C to +85°C. It is housed in a surface-mount SOT-23-3 package.

Supervisors Feature Summary

• Provides active high push-pull reset signal
• Single-channel voltage monitoring capability
• Integrated reset timeout circuitry

Supervisors Applications

• Microprocessor system supervision
• Battery-powered equipment power management
• Portable instrumentation reset control

Supervisors Procurement Notes

Verify the specific suffix 'U' against official datasheets to confirm package and tape-and-reel specifications. Confirm availability status as distribution data may vary. Ensure compatibility with existing PCB footprints for the SOT-23-3 package before procurement.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor with an active high output is required. The 4.62V threshold suits 5V systems. Consider the SOT-23-3 package size constraints and the 100ms reset delay duration relative to system startup requirements.

Supervisors Part Context

Part of the Maxim Integrated EconoReset family, designed for cost-sensitive applications requiring basic power supply monitoring. The DS1812 series offers various threshold voltages and output polarities to accommodate different logic families and supply rails without external components.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same series or other manufacturers offering similar active high push-pull supervisors in SOT-23-3 packages. Verify threshold voltage tolerance matches application needs.
