MAX6309UK32D1+T

Supervisors Overview

The MAX6309UK32D1+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range of up to 5.5V and features a fixed reset threshold of 3.2V. The device provides an active low, push-pull output with a manual reset input capability. It consumes 8µA of operating current and includes a 1.4ms reset delay time. The component is housed in a SOT-23-5 package and supports surface mount installation.

Supervisors Feature Summary

• Monitors multiple power supply inputs simultaneously
• Features a manual reset input for system 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 D1 against official Analog Devices documentation to confirm the exact factory-programmed threshold voltage associated with this variant. Ensure the lead-free (+) designation matches project requirements. Confirm availability status as distribution channels may indicate limited stock or special order conditions for this specific part number.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required in space-constrained designs. The SOT-23-5 package offers a compact footprint suitable for portable electronics. Consider the 8µA quiescent current for battery-operated systems. Verify that the 3.2V threshold aligns with the specific supply rail being protected.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input, programmable reset ICs. These devices are engineered to assert a system reset if any monitored supply falls outside its programmed threshold. The series is characterized by low power consumption and transient immunity, making it suitable for robust system supervision in consumer and industrial electronics.

Supervisors Replacement Considerations

Consult official cross-reference data for verified substitutes. Generic family members like MAX6309 variants with different thresholds (e.g., UK27, UK34) require verification of threshold compatibility.
