MAX6306UK46D3+T

Supervisors Overview

The MAX6306UK46D3+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed reset thresholds of 3.3V and 5V. The device provides an active low, open-drain output and includes a manual reset input. It operates within a supply voltage range up to 5.5V, consumes 8µA of quiescent 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 manual reset input for user-initiated control
• 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 supervisory circuits

Supervisors Procurement Notes

Verify the specific suffix D3+T against the manufacturer's datasheet to confirm the exact threshold voltage configuration and package variant. Confirm RoHS compliance status through official documentation before integration. Check availability status as distribution may vary by region.

Supervisors Selection Notes

Select this component when dual-supervision of distinct voltage levels is required without external programming resistors. Ensure the application environment remains within the specified commercial temperature range. Verify that the open-drain output type matches the downstream logic requirements.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input programmable reset ICs. These devices are engineered for portable electronics where space and power consumption are critical constraints. The series utilizes a compact SOT-23-5 package to minimize board footprint while maintaining robust supervisory functions.

Supervisors Replacement Considerations

Other variants within the MAX6305–MAX6313 family offer different fixed threshold combinations. Verify pin compatibility and electrical specifications before substituting with other members of the series.
