MAX6307UK45D1-T

Supervisors Overview

The MAX6307UK45D1-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with a fixed reset threshold voltage of 4.5V. The device provides an active-low, open-drain reset output and operates within a supply voltage range up to 5.5V. It includes a programmable reset delay time of 1.4 ms. The component is housed in a compact SOT-23-5 package, suitable for surface-mount applications.

Supervisors Feature Summary

• Monitors two independent power supply rails simultaneously
• Provides active-low open-drain reset signal generation
• Features a programmable reset delay timer for controlled assertion timing
• Operates with low supply current consumption

Supervisors Applications

• Personal computer system power monitoring
• Portable electronic devices requiring multi-voltage supervision
• Industrial control systems with multiple power domains
• Embedded systems needing reliable reset sequencing

Supervisors Procurement Notes

Verify the specific suffix D1-T against official Analog Devices documentation to confirm the exact threshold voltage and delay characteristics. Ensure compatibility with the target PCB footprint for the SOT-23-5 package. Confirm lead-free status if required by environmental regulations, as variations exist within the MAX6307 family.

Supervisors Selection Notes

Select this part when dual-supervision is required for distinct voltage rails such as 5V and 3.3V. The fixed 4.5V threshold suits applications where one rail requires strict monitoring while the other may be less critical or monitored differently. Consider the 1.4ms delay for system startup stability requirements.

Supervisors Part Context

This component belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input, programmable reset ICs from Maxim Integrated. These devices are engineered for microprocessor supervisory roles, offering flexibility in monitoring configurations compared to single-channel supervisors.

Supervisors Replacement Considerations

Cross-reference with MAX6307UK45D2+T or MAX6307UK45D4-T for similar functionality but verify threshold voltages and delay times differ. Check MAX6307UK26D1-T for alternative threshold options within the same package.
