MAX6306UK31D3-T

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, consumes 8µA of supply current, and offers a reset delay time of 1.4ms. The component is housed in a SOT-23-5 package and supports operation from 0°C to +70°C.

Supervisors Feature Summary

• Monitors multiple power supplies simultaneously to assert system reset if any supply falls outside programmed thresholds
• Includes manual reset input for external control of the reset state
• Designed to ignore fast transients on monitored supplies to prevent false resets

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 specific suffix D3 against official documentation to confirm the exact threshold voltage configuration, as suffixes often denote specific factory-programmed values. Confirm RoHS compliance status and lead-free designation directly with the manufacturer or authorized distributors. Check for obsolescence notices or lifecycle status updates prior to finalizing procurement plans.

Supervisors Selection Notes

Select this component when simultaneous monitoring of two distinct voltage rails is required. Ensure the fixed 3.08V and 5V thresholds align with the target power supply specifications. Consider the SOT-23-5 package size constraints and the 0°C to +70°C operating temperature range during board layout and thermal design.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input, programmable reset ICs manufactured by Analog Devices / Maxim Integrated. These devices are specifically engineered for portable applications due to their low power consumption and small footprint. The series allows for monitoring various standard voltage levels in embedded systems.

Supervisors Replacement Considerations

Consult official cross-reference data for verified substitutes. Generic equivalents may not match the specific dual-input threshold configuration or transient immunity characteristics.
