DS1836A-10+

Supervisors Overview

The DS1836A-10+ is a MicroManager supervisory circuit designed for monitoring power supply voltages in microprocessor systems. It operates within a supply voltage range of 1.2 V to 5.5 V and features a threshold voltage of 4.37 V. The device provides a reset delay time of 500 ms and includes battery backup switching capabilities. It supports manual reset inputs and offers open-drain CMOS outputs. The component functions across an industrial temperature range from -40°C to +85°C, ensuring reliable performance in demanding environments.

Supervisors Feature Summary

• Monitors power supply voltage levels to ensure system stability during transients
• Provides orderly shutdown control for nonvolatile memory applications via battery backup switching
• Includes manual reset input for external override capability

Supervisors Applications

• Microprocessor system power supervision
• Nonvolatile memory protection in embedded systems
• Battery-operated handheld applications requiring low-power stop mode control

Supervisors Procurement Notes

Verify the specific suffix designation as the provided model indicates a plus sign which may denote lead-free status or package variation compared to the base part number. Confirm availability status as this series has been subject to discontinuation notices by the manufacturer. Ensure compatibility with existing PCB footprints and verify that the required reset delay and threshold specifications meet the target design constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with battery backup functionality is required. The 4.37 V threshold suits standard 5 V logic systems. Consider the 500 ms reset delay for systems needing extended stabilization time. Verify that the open-drain output interface matches the microprocessor reset pin requirements. Check if the manual reset feature is necessary for the specific application safety protocols.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroManager family, which integrates voltage supervision, battery backup switching, and write-protection controls. These circuits are designed to protect data integrity in volatile memory systems during power failures. The DS1836 variant specifically focuses on single-supply monitoring with manual reset options, distinguishing it from multi-channel or watchdog-enabled counterparts in the broader PMIC portfolio.

Supervisors Replacement Considerations
