DS1836B-10+

Supervisors Overview

The DS1836B-10+ is a MicroManager supervisory circuit designed for 3.3V and 5V systems. It integrates a precision temperature-compensated voltage reference, comparator, and power-fail detection to monitor VCC status. The device features an internal power switch that automatically transitions to a battery supply when VCC drops below specified thresholds (2.6V for 3.3V versions). It asserts a reset signal during out-of-tolerance conditions and maintains the reset state for 350 ms after VCC returns to normal operation.

Supervisors Feature Summary

• Integrates precision temperature-compensated voltage reference and sensor
• Internal power switch switches to battery supply at low VCC levels
• Asserts reset signals during power transients and out-of-tolerance conditions
• Maintains reset for 350 ms after VCC returns to in-tolerance condition

Supervisors Applications

• Systems designed to operate with dual power supplies
• PIC microprocessor applications
• Battery backup systems requiring seamless power transition

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm RoHS compliance status and check current lifecycle status as this series may be discontinued or subject to limited availability. Ensure the specific suffix matches the required voltage threshold and package type for your design.

Supervisors Selection Notes

Select this component for applications requiring integrated power monitoring and battery switching without discrete components. Choose based on the required operating voltage range (3.3V or 5V) and the need for a CMOS reset output. Consider the 8-pin SOIC package for space-constrained surface mount designs.

Supervisors Part Context

The DS1836B-10+ belongs to the MicroManager family of supervisory circuits from Analog Devices/Maxim Integrated. These devices are engineered to simplify system design by combining voltage monitoring, reset generation, and power switching functions into a single IC, reducing the bill of materials for embedded systems.

Supervisors Replacement Considerations

Public confirmed substitute part numbers: DS1836A-10+, DS1836C-10+, DS1836D-10+. Verify compatibility regarding voltage thresholds and package dimensions before substitution.
