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 3.3 V and 5 V. The device provides an active low, open-drain output and includes a manual reset input. It operates within a supply voltage range up to 5.5 V and consumes 8 µA of quiescent current. The reset delay time is specified at 1.57 s, and the overvoltage threshold is 3.126 V. Power dissipation is rated at 571 mW. The component is housed in a SOT-23-5 package and supports surface mount installation.

Supervisors Feature Summary

• Monitors multiple power supplies by asserting system reset if any supply falls outside programmed thresholds
• Designed to ignore fast transients on monitored supplies for stable operation
• Includes manual reset input for user-initiated system control

Supervisors Applications

• Monitoring 5V and 3.3V supplies in personal computer systems
• Portable applications requiring low supply current and small package size

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and lead-free designation prior to integration. Check for obsolescence notices as this part may be discontinued. Ensure packaging specifications match design requirements. Validate datasheet revisions against production batches.

Supervisors Selection Notes

Select this component when dual-supervision capability is required for distinct voltage rails. The fixed threshold configuration eliminates external resistor networks. Consider the SOT-23-5 footprint for space-constrained designs. Verify that the 1.57 s reset delay aligns with system startup timing requirements. Ensure operating temperature range meets environmental specifications.

Supervisors Part Context

This device belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input programmable reset ICs. These circuits are optimized for monitoring more than one power supply simultaneously. The series emphasizes low power consumption and transient immunity. Analog Devices / Maxim Integrated manufactures these supervisory components for embedded and computing applications.

Supervisors Replacement Considerations

Consult official documentation for direct pin-compatible substitutes within the MAX6305–MAX6313 family. Verify threshold voltages and package dimensions before substitution. No public confirmed substitute part numbers are available in the provided data.
