MAX6309UK27D2

Supervisors Overview

The MAX6309UK27D2 is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed reset thresholds of 2.7V and 2.741V. The device operates within a supply voltage range up to 5.5V and provides an active low, push-pull output. It includes a manual reset input and has a reset delay time of 1.4ms. The component is housed in a SOT-23-5 package and supports surface mount installation.

Supervisors Feature Summary

• Monitors multiple power supplies by asserting system reset if any supply falls outside programmed thresholds
• Designed to ignore fast transients on monitored supplies for stable operation
• Includes manual reset input capability for external control

Supervisors Applications

• Monitoring 5V and 3.3V supplies in personal computer systems
• Portable applications requiring low supply current
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify the specific suffix D2 against official Analog Devices documentation to confirm threshold voltages and pinout configuration. Ensure compatibility with the SOT-23-5 package requirements. Confirm RoHS compliance status through manufacturer datasheets before integration into designs.

Supervisors Selection Notes

Select this component when monitoring dual voltage rails such as 5V and 3.3V simultaneously. The fixed thresholds eliminate the need for external programming resistors. Consider the 1.4ms reset delay and active low output type for interface compatibility with target logic families.

Supervisors Part Context

Part of the MAX6305–MAX6313 series of 5-pin, multiple-input, programmable reset ICs. These devices are optimized for portable applications due to low supply current consumption and compact packaging. The series allows monitoring of more than one power supply within a single small footprint.
