MAX6306UK31D3+

Supervisors Overview

The MAX6306UK31D3+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed reset thresholds of 3.08V and 5V. The device provides an active-low, open-drain reset output and includes a manual reset input. It operates within a supply voltage range up to 5.5V and consumes low quiescent current. The component is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Monitors multiple power supply rails simultaneously
• Includes manual reset input for system control
• Asserts reset when monitored voltages fall below programmed thresholds
• Designed to ignore fast transients on monitored supplies

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable applications requiring low supply current
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging, as the base part number may refer to tube packaging. Confirm RoHS compliance status through official documentation. Check for obsolescence or limited availability status directly with Analog Devices or authorized distributors before procurement planning.

Supervisors Selection Notes

Select this component when dual-supervision capability is required for distinct voltage levels. Ensure the fixed 3.08V and 5V thresholds align with target supply rails. Consider the SOT-23-5 package size constraints and the need for a manual reset interface in the design architecture.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input programmable reset ICs. These devices are specifically engineered for portable and PC applications where monitoring multiple supplies from a small footprint is critical. The family offers various threshold combinations and transient immunity features.

Supervisors Replacement Considerations

Cross-reference with other MAX6306 variants (e.g., MAX6306UK49D3+) if different threshold combinations are acceptable. Verify pinout compatibility with SOT-23-5 packages. Check for updated lead-free versions if environmental compliance is mandatory.
