MAX6306UK44D3

Supervisors Overview

The MAX6306UK44D3 is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features a fixed reset threshold voltage of 4.4V and supports a maximum supply voltage of 5.5V. The device provides an active-low, open-drain output with a manual reset input. It operates within a temperature range of 0°C to +70°C and consumes low supply current. Packaged in a compact SOT-23-5 surface-mount case, it asserts a system reset if any monitored supply falls outside the programmed threshold.

Supervisors Feature Summary

• Monitors multiple power supply inputs simultaneously
• Includes manual reset input for user-initiated control
• Features active-low open-drain reset output
• Designed to ignore fast transients on monitored supplies

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable electronic devices requiring low supply current
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and lead-free specifications against the official datasheet. Check for obsolescence notices as this part may be discontinued. Ensure the SOT-23-5 package matches design requirements. Validate electrical parameters against specific application needs before integration.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required. The fixed 4.4V threshold suits applications needing precise supervision at that level. Consider the SOT-23-5 package for space-constrained designs. Verify compatibility with system logic levels due to the open-drain output configuration. Evaluate operating temperature range against environmental conditions.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input, programmable reset ICs from Maxim Integrated. These devices are specifically engineered for portable applications due to their low power consumption and small footprint. The series offers factory-programmed thresholds ranging from 2.5V to 5.0V in 100mV increments, providing flexibility for various power supply architectures without external components.

Supervisors Replacement Considerations

Cross-reference with other MAX6306 variants having different threshold voltages if 4.4V is not suitable. Verify pinout compatibility with existing PCB layouts. Check for updated versions within the MAX6305–MAX6313 family that may offer improved specifications or availability.
