DS1812R-10-U

Supervisors Overview

The DS1812R-10-U is a voltage monitor supervisor circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1V to 5.5V and features a single monitored input with a threshold accuracy of 10%. The device provides an active high, push-pull output type and includes a reset delay time of 100ms minimum. It functions without manual reset or watchdog timer capabilities. The component is designed for surface mount installation in SOT-23-3 packages and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides voltage supervision with active high push-pull output
• Operates across a wide supply voltage range from 1V to 5.5V
• Features a minimum reset delay time of 100ms

Supervisors Applications

• Embedded system power monitoring
• Microcontroller reset generation
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix 'U' against official datasheets to confirm package and tape/reel specifications. Confirm RoHS compliance status as it may vary by production batch. Check current lifecycle status as components in this series may be subject to discontinuation or limited availability. Ensure the selected variant matches the required threshold voltage and output configuration for the target application design.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor with active high output is required. Verify that the 10% threshold accuracy meets the system's voltage tolerance requirements. Ensure the SOT-23-3 package fits the PCB layout constraints. Consider the 100ms minimum reset delay to ensure stable power-up sequences for connected logic devices.

Supervisors Part Context

This part belongs to the DS1812 EconoReset series, which offers basic voltage monitoring functionality. It is distinct from variants with different thresholds or output polarities. The 'R' indicates the SOT-23-3 package, while '10' denotes the specific threshold voltage setting. This series is designed for cost-sensitive applications requiring reliable power supervision.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the DS1812 family with matching threshold voltages. Verify equivalent output types and reset delays. Consult manufacturer cross-reference guides for updated alternatives if the original part is discontinued.
