MAX6305UK00D2-T

Supervisors Overview

The MAX6305UK00D2-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed thresholds of 3.3 V and 5 V. The device provides an active low, open-drain reset output with a typical delay time of 1.4 ms. It operates within a maximum supply voltage of 5.5 V and consumes 8 uA of operating supply current. The component is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Monitors two independent power supply rails simultaneously
• Provides active low open-drain reset signal assertion
• Designed to ignore fast transients on monitored supplies

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable applications requiring low supply current
• Microprocessor system supervision

Supervisors Procurement Notes

Verify the exact suffix against official documentation, as distributor listings may vary. Confirm RoHS compliance status and lead-free specifications directly from the manufacturer datasheet. Check for obsolescence notices or product change notifications prior to procurement. Ensure the specific threshold voltages match the design requirements.

Supervisors Selection Notes

Select this component when dual-rail supervision is required in a small footprint. Verify that the open-drain output configuration matches the system logic interface. Ensure the 1.4 ms reset delay meets the timing constraints of the target microprocessor. Confirm compatibility with the available supply voltage range up to 5.5 V.

Supervisors Part Context
