MAX6306UK25D3+T

Supervisors Overview

The MAX6306UK25D3+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed reset thresholds of 2.5V and 3.3V. The device provides an active-low, open-drain reset output and includes a manual reset input. It operates within a supply voltage range up to 5.5V, consumes 8µA of supply current, and offers a reset delay time of 1.4ms. Packaged in a SOT-23-5 surface-mount case, it supports operation from 0°C to +70°C.

Supervisors Feature Summary

• Monitors multiple power supplies simultaneously for system integrity
• Includes a manual reset input for user-initiated control
• Provides an active-low, open-drain reset signal output

Supervisors Applications

• Monitoring 5V and 3.3V rails in personal computer systems
• Portable applications requiring low supply current
• Systems needing protection against out-of-specification voltages

Supervisors Procurement Notes

Verify the exact suffix D3+T to confirm the specific threshold configuration and lead-free status. Confirm availability as distribution channels may list this part as limited or discontinued. Ensure the SOT-23-5 package matches your PCB footprint requirements before ordering.

Supervisors Selection Notes

Select this component when dual-supervision is required for distinct voltage levels such as 2.5V and 3.3V. It is suitable for designs prioritizing low quiescent current and compact SOT-23-5 packaging over higher temperature ranges or watchdog timer functionality.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input programmable reset ICs. These devices are engineered to ignore fast transients on monitored supplies while asserting a reset if any voltage falls outside its programmed threshold.

Supervisors Replacement Considerations

Check MAX6306EUK25D3+T for identical electrical specifications but potentially different environmental ratings. Verify pinout compatibility with other MAX6306 variants before substitution.
