MAX6306UK25D1

Supervisors Overview

The MAX6306UK25D1+T is a CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single power supply with a fixed reset threshold voltage of 2.5V. The device features an active-low, open-drain output and includes a manual reset input for system control. It operates within a temperature range of 0°C to +70°C and consumes a typical supply current of 8µA. Packaged in a compact SOT-23-5 surface-mount case, it provides reliable supervision for portable electronics.

Supervisors Feature Summary

• Features factory-programmable reset thresholds
• Includes manual reset input capability
• Designed to ignore fast transients on monitored supplies

Supervisors Applications

• Portable consumer electronics
• Battery-powered instrumentation
• Personal computer systems
• Industrial control systems

Supervisors Procurement Notes

Verify the specific suffix D1 against official Maxim Integrated documentation to confirm the exact threshold voltage and package variant. Ensure compatibility with the target operating temperature range of 0°C to +70°C. Confirm RoHS compliance status for environmental regulations. Check for obsolescence notices as this component series may have limited availability from original manufacturers.

Supervisors Selection Notes

Select this component when a fixed 2.5V threshold is required for single-supply monitoring. Consider the SOT-23-5 package for space-constrained PCB layouts. Evaluate the low quiescent current for battery life optimization. Verify that the open-drain output configuration matches the system's logic requirements.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input programmable reset ICs. These devices are designed to monitor more than one power supply, making them suitable for complex systems requiring redundant power supervision. The family offers various threshold options to accommodate different voltage rails.

Supervisors Replacement Considerations

Direct substitutes include other parts from the MAX6305–MAX6313 series with matching 2.5V thresholds and SOT-23-5 packages. Verify pinout compatibility and electrical specifications before substitution.
