DS1836C-10+

Supervisors Overview

The DS1836C-10+ is a MicroManager supervisory circuit designed for single-input voltage monitoring. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 4.37 V. The device provides a CMOS open-drain output with a reset delay time of 500 ms. It includes power-fail detection capabilities and supports battery backup switching. The component functions reliably across an industrial temperature range from -40°C to +85°C, consuming 55 µA of operating current.

Supervisors Feature Summary

• Monitors a single voltage input against a fixed threshold to ensure system stability during power transients.
• Generates a reset signal via an open-drain CMOS output when the monitored voltage falls below the specified level.
• Detects power failures to provide advance warning before the supply drops below the reset threshold.

Supervisors Applications

• Embedded systems requiring reliable microprocessor reset generation
• Battery-powered devices utilizing backup switching mechanisms
• Industrial control units needing supervision over critical voltage rails

Supervisors Procurement Notes

Verify the exact suffix designation, as the C variant may differ in package or temperature rating from the AS version. Confirm availability status due to potential end-of-life constraints. Ensure the selected package matches the PCB footprint requirements. Validate RoHS compliance documentation for the specific manufacturing batch.

Supervisors Selection Notes

Select this component when a fixed 4.37 V threshold is required for single-supervision applications. Consider the 500 ms reset delay for timing-sensitive designs. Evaluate the open-drain output compatibility with the target logic levels. Assess the 55 µA quiescent current against strict power budget constraints.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroManager family, specialized for supervising power supplies in embedded environments. It integrates essential monitoring functions into a compact surface-mount package. The series is engineered to maintain system integrity by managing resets and power-fail warnings automatically.

Supervisors Replacement Considerations

The DS1836AS-10+ serves as a direct functional substitute within the same product line. Verify that the alternative package type aligns with existing board layouts. Confirm identical electrical specifications to ensure seamless integration without design modifications.
