DS1836C-10

Supervisors Overview

The DS1836C-10 is a MicroManager supervisory circuit designed for 5V and 3.3V systems. It monitors VCC voltage, generating a reset signal when out of tolerance. The device switches to a battery backup supply at 3.8V (2.6V for 3.3V versions) and returns to VCC above 3.9V (2.8V). It features a CMOS reset output with a 350ms delay after power recovery. Operating temperature range is -40°C to +85°C.

Supervisors Feature Summary

• Monitors system voltage and asserts reset during transients
• Switches to battery backup supply upon voltage degradation
• Maintains reset state for specified duration after power restoration

Supervisors Applications

• Systems requiring dual power supply management
• PIC microprocessor applications
• Battery-operated handheld devices
• Nonvolatile memory control circuits

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm package type availability matches design requirements. Check RoHS compliance documentation against specific manufacturing lot dates. Validate operating temperature range suitability for target environment conditions prior to integration.

Supervisors Selection Notes

Select this component for applications requiring precise voltage monitoring without manual reset inputs. Ensure the 350ms reset delay aligns with system startup timing requirements. Verify that the CMOS output interface is compatible with the downstream logic family. Consider the 8-pin SOIC or DIP packaging options based on board space constraints.

Supervisors Part Context

Part of the Maxim Integrated MicroManager family, providing integrated power-fail detection and battery switching. Designed to reduce discrete component count in embedded systems. Offers precision temperature-compensated reference for accurate threshold detection across industrial temperature ranges.

Supervisors Replacement Considerations

DS1836AS-10: Similar function with different suffix indicating tape/reel packaging option. DS1236A-10: Enhanced version with additional watchdog timer functionality. Verify pin compatibility and electrical specifications before substitution.
