MXD1810XR41

Supervisors Overview

The MXD1810XR41 is a precision microprocessor reset supervisor IC manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features a factory-trimmed threshold voltage of 4.12 V, suitable for 5V systems. The device provides an active-low push-pull RESET output with a typical reset delay time of 100 ms. It is designed for surface-mount installation in SC-70-3 packages and functions reliably across an extended temperature range from -40°C to +105°C.

Supervisors Feature Summary

• Provides precise voltage supervision for microprocessor systems
• Features a factory-trimmed threshold voltage for accuracy
• Delivers an active-low push-pull reset signal
• Operates with low power consumption

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Power management units requiring voltage supervision
• Industrial control systems operating at 5V logic levels

Supervisors Procurement Notes

Verify the specific suffix (e.g., XR41) to confirm package type and temperature grade. Confirm RoHS compliance status as required by project specifications. Check for obsolescence or lifecycle status, as some variants may be discontinued. Ensure the supplier provides valid datasheets matching the exact part number to avoid pinout or electrical characteristic mismatches during integration.

Supervisors Selection Notes

Select this component when a fixed 4.12V threshold is required for 5V system monitoring. The SC-70-3 package is ideal for space-constrained designs. Consider the active-low output polarity and push-pull drive capability against interface requirements. Verify that the 100ms reset delay meets the target processor's startup timing constraints.

Supervisors Part Context

This part belongs to the MXD1810 series of supervisors. It is distinct from similar models like the MXD1812 which may offer different thresholds or outputs. The 'XR41' designation typically indicates the SC-70-3 package and specific temperature range. It serves as a dedicated voltage monitor rather than a general-purpose comparator.

Supervisors Replacement Considerations

Direct substitutes include other Maxim/Analog Devices supervisors with identical 4.12V thresholds and SC-70-3 packaging. Cross-reference pinouts carefully when considering third-party equivalents to ensure compatibility with existing PCB layouts.
