MAX6306UK47D2+

Supervisors Overview

The MAX6306UK47D2+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 4.7V. The device provides an active low, open-drain output and includes a manual reset input. It consumes 8µA of supply current and functions across a temperature range of 0°C to +70°C. Packaged in a compact SOT-23-5 footprint, it asserts a system reset if monitored voltages fall outside programmed thresholds.

Supervisors Feature Summary

• Monitors multiple power supply inputs for system integrity
• Provides active low open-drain reset signal output
• Includes manual reset input capability
• 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 exact suffix against official documentation, as availability varies by region. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Check for obsolescence notices or limited supply warnings prior to procurement planning.

Supervisors Selection Notes

Select this component when dual-input supervision is required with a specific 4.7V threshold. Ensure the application environment stays within the specified 0°C to +70°C operating temperature range. Verify that the active low open-drain output configuration matches the downstream logic requirements.

Supervisors Part Context

Part of the MAX6305–MAX6313 family of 5-pin, multiple-input programmable reset ICs. These devices are optimized for portable applications due to low power consumption and small package size. They offer factory-programmed thresholds from 2.5V to 5.0V in 100mV increments.

Supervisors Replacement Considerations

Check for MAX6306 variants with different threshold codes (e.g., UK49, UK38) if voltage levels differ. Consider MAX6388 series for adjustable thresholds or wider temperature ranges if specifications exceed this part's limits.
