MAX6306UK47D3+T

Supervisors Overview

The MAX6306UK47D3+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two voltage monitoring channels with a fixed threshold of 4.7V and an adjustable threshold. The device provides an active-low, open-drain reset output and includes a manual reset input. Packaged in a compact SOT-23-5 format, it operates within a supply voltage range up to 5.5V. Designed for low quiescent current consumption, it supports portable applications while ignoring fast transients on monitored supplies.

Supervisors Feature Summary

• Dual-channel voltage monitoring with one fixed and one adjustable threshold
• Active-low open-drain reset output with manual reset capability
• Transient immunity for reliable operation in noisy environments

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable electronic devices requiring low standby current
• Embedded systems requiring multi-supervisory circuit protection

Supervisors Procurement Notes

Verify the specific suffix D3 indicates the factory-programmed threshold configuration. Confirm RoHS compliance status through official Analog Devices documentation. Check current availability as distribution status may vary by region. Ensure the SOT-23-5 package matches your PCB footprint requirements before procurement.

Supervisors Selection Notes

Select this component when dual-supply supervision is required in space-constrained designs. The fixed 4.7V threshold suits specific rail monitoring needs. Consider the adjustable channel for custom threshold requirements. Verify that the open-drain output interface aligns with the target system logic levels.

Supervisors Part Context

Part of the MAX6305–MAX6313 family of 5-pin multiple-input programmable reset ICs. These devices are optimized for monitoring more than one power supply simultaneously. The series offers factory-programmed thresholds ranging from 2.5V to 5.0V in 100mV increments.

Supervisors Replacement Considerations

Cross-reference with other MAX6306 variants having different threshold suffixes if voltage requirements change. Verify pinout compatibility with existing SOT-23-5 footprints. Ensure functional equivalence regarding reset delay and quiescent current specifications.
