DS1836DS-10+

Supervisors Overview

The DS1836DS-10+ is a MicroManager supervisory circuit designed for monitoring voltage levels in embedded systems. It provides precise power-fail detection and reset generation with a threshold of 4.37V. The device features an open-drain CMOS output, a reset delay of 500ms, and operates within a supply range of 1.2V to 5.5V. It consumes 55µA during operation and includes battery backup switching capabilities. The component is housed in an 8-pin SOIC package and supports industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Monitors VCC voltage and generates internal power-fail signals when out-of-tolerance conditions are detected
• Switches to battery supply automatically when VCC drops below the threshold level
• Maintains reset state for a specified duration after VCC returns to normal operating conditions

Supervisors Applications

• Microprocessor system supervision
• Battery-powered handheld applications requiring orderly shutdown
• Systems utilizing dual power supplies

Supervisors Procurement Notes

Verify availability status as this part may be discontinued or subject to limited supply constraints. Confirm RoHS compliance details and specific suffix variations against official Analog Devices documentation before procurement. Ensure the ordering information matches the required package type and temperature range specifications.

Supervisors Selection Notes

Select this component for applications requiring accurate 10% power supply monitoring and low standby current consumption. Consider the 8-pin SOIC package for space-constrained designs. Verify that the 500ms reset timeout aligns with system startup requirements. Evaluate the need for manual reset functionality if external override is necessary.

Supervisors Part Context

The DS1836 series belongs to Maxim Integrated's MicroManager family, designed to simplify power management in microprocessor-based systems. These devices integrate voltage monitoring, reset generation, and battery backup switching into a single IC, reducing the need for discrete components and simplifying board layout for reliable system operation.

Supervisors Replacement Considerations

Public confirmed substitutes include DS1836AS-10+ and DS1836BS-10+. Verify pin compatibility and electrical parameter alignment with original datasheets before substitution.
