DS1836BS-10

Supervisors Overview

The DS1836BS-10 is a MicroManager supervisor IC manufactured by Analog Devices Inc./Maxim Integrated. It integrates a precision temperature-compensated voltage reference and comparator to monitor VCC status, generating an internal power-fail signal when out-of-tolerance conditions occur. The device features a true 3V operation power switch that automatically switches to a battery supply when VCC drops below 3.8V (2.6V for 3.3V versions) and resumes VCC supply when VCC exceeds 3.9V (2.8V for 3.3V versions). It provides a CMOS reset output with a minimum reset timeout of 200ms and operates within a temperature range of -40°C to +85°C in an 8-SOIC package.

Supervisors Feature Summary

• Integrates a precision temperature-compensated voltage reference and comparator circuit for accurate voltage monitoring
• Features a true 3V operation power switch that seamlessly transitions between main and backup battery supplies based on voltage thresholds
• Maintains the reset signal active for a specified duration after VCC returns to an in-tolerance condition to ensure system stability

Supervisors Applications

• Systems designed to operate with dual power supplies
• PIC microprocessor applications requiring reliable power management
• Embedded systems needing protection against power transients and brownouts

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to the discontinued status of this part number. Confirm that the specific suffix corresponds to the required voltage threshold and package variant, as generic family data may not reflect exact electrical characteristics. Ensure storage and handling comply with moisture sensitivity level requirements prior to assembly to prevent damage during reflow soldering processes.

Supervisors Selection Notes

Select this component for applications requiring integrated power switching and supervision in a single package. Consider the specific voltage thresholds associated with the 'B' suffix variant compared to other series members. Evaluate the 8-SOIC surface mount package constraints against available board space. Verify compatibility with the target microprocessor's reset input requirements and operating temperature range before finalizing the design.

Supervisors Part Context

The DS1836 belongs to the MicroManager series, which combines power-supply monitoring and control functions. This series is designed to reduce discrete component count in embedded systems. The DS1836BS-10 specifically targets applications needing robust power fail detection and automatic switchover capabilities, distinguishing it from standard supervisors that lack integrated power switching functionality.
