MAX6306UK29D3+T

Supervisors Overview

The MAX6306UK29D3+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range up to 5.5V and features a fixed reset threshold of 2.9V. The device provides an active low, open-drain output with a manual reset input. It consumes 8µA of supply current and offers a reset delay time of 1.4ms. Packaged in a compact SOT-23-5 format, it supports operation across industrial temperature ranges.

Supervisors Feature Summary

• Monitors multiple power supply inputs for system integrity
• Includes a manual reset input for user control
• Provides active low open-drain reset output signal

Supervisors Applications

• Portable computers and battery-powered equipment
• Multivoltage systems such as 3V/5V or 5V/12V configurations
• Embedded control systems requiring reliable supervision

Supervisors Procurement Notes

Verify the exact suffix D3 against official Analog Devices documentation to confirm the specific factory-set threshold voltage and timeout delay. Confirm RoHS compliance status and lead-free designation directly from the manufacturer datasheet before procurement. Ensure the SOT-23-5 package dimensions match your PCB footprint requirements.

Supervisors Selection Notes

Select this component when monitoring multiple rails is required without external programming components. The fixed 2.9V threshold suits applications where this specific voltage level defines the valid operating window. Consider the 8µA quiescent current for battery-sensitive designs. Verify that the open-drain output interface aligns with the downstream logic requirements.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input programmable reset ICs. These devices are engineered to ignore fast transients on monitored supplies. The series is optimized for portable applications due to low supply current and small package size, ensuring system resets occur if any monitored supply falls outside programmed thresholds.

Supervisors Replacement Considerations

Cross-reference with other MAX6306 variants having different threshold suffixes if the 2.9V level is unsuitable. Verify pinout compatibility with alternative supervisors in the same SOT-23-5 package family.
