MAX6306UK31D4+

Supervisors Overview

The MAX6306UK31D4+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed reset thresholds of 3.3V and 5V. The device provides an active low, open-drain 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 1.57s. The component is housed in a compact SOT-23-5 package.

Supervisors Feature Summary

• Monitors multiple power supplies simultaneously for system integrity
• Includes a manual reset input for user-initiated control
• Provides active low, open-drain reset output signal

Supervisors Applications

• Personal computer systems requiring dual voltage monitoring
• Portable applications due to low supply current consumption
• Systems needing protection against out-of-specification power levels

Supervisors Procurement Notes

Verify the specific suffix D4+T against official Analog Devices documentation to confirm threshold voltages and package type. Confirm RoHS compliance status as indicated in the datasheet. Check current lifecycle status, as this part may be discontinued or subject to limited availability depending on the manufacturing date code.

Supervisors Selection Notes

Select this component when simultaneous monitoring of two distinct voltage rails is required. Ensure the fixed 3.3V and 5V thresholds align with the target power supply specifications. Verify that the SOT-23-5 package fits the board layout constraints and that the 1.57s reset delay meets the system startup timing requirements.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input, programmable reset ICs manufactured by Maxim Integrated, now part of Analog Devices. These devices are engineered to ignore fast transients on monitored supplies, making them suitable for noisy environments. The series is characterized by low power consumption and small form factors ideal for portable electronics.

Supervisors Replacement Considerations

Consult the official MAX6306 datasheet for cross-reference information. Potential substitutes must match the SOT-23-5 package, dual-input capability, and similar threshold voltages. Verify functional compatibility before replacing.
