MAX6307UK47D1-T

Supervisors Overview

The MAX6307UK47D1-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range of 1 V to 5.5 V and features an active-low, open-drain reset output. The device monitors two inputs with a fixed threshold voltage of 4.75 V. It includes a programmable reset delay time of 140 ms and consumes low supply current. The component is housed in a compact SOT-23-5 package and supports surface-mount installation.

Supervisors Feature Summary

• Monitors up to two independent power supply rails for system integrity
• Provides active-low open-drain reset signal when voltages exceed thresholds
• Features low quiescent current consumption suitable for portable applications
• Includes programmable reset delay timer to prevent false resets

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V supplies
• Portable electronic devices requiring low-power supervision
• Embedded systems needing multi-voltage oversight

Supervisors Procurement Notes

Verify the specific suffix D1 corresponds to the 4.75 V threshold and 140 ms delay configuration. Confirm RoHS compliance status as datasheets may vary by revision. Ensure the SOT-23-5 package matches your PCB footprint requirements. Check operating temperature range specifications against your environmental constraints.

Supervisors Selection Notes

Select this part when dual-supervision is required without manual reset functionality. Compare threshold voltages against other MAX6307 variants if different trip points are needed. Consider the open-drain output requirement for pull-up resistor integration. Evaluate the 140 ms delay against system startup timing requirements.

Supervisors Part Context

This component belongs to the MAX6305–MAX6313 family of supervisory circuits from Maxim Integrated. These devices are engineered for monitoring multiple power rails in complex digital systems. The family offers various threshold combinations and delay options to suit diverse application needs while maintaining a small form factor.

Supervisors Replacement Considerations

Check MAX6307UK47D2-T or MAX6307UK47D3-T for alternative delay times. Verify MAX6307UK47D4-T if a different delay specification is acceptable. Ensure any substitute maintains the 4.75 V threshold and SOT-23-5 package.
