MAX6306UK30D2+T

Supervisors Overview

The MAX6306UK30D2+T is a CMOS microprocessor supervisory circuit designed to monitor power supply voltages. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold of 3.0V. The device provides an active-low, push-pull reset output with a typical delay of 140ms. It includes a manual reset input for system control and supports operation across an industrial temperature range from -40°C to +85°C. Packaged in a compact SOT-23-5 outline, it consumes low quiescent current suitable for portable applications.

Supervisors Feature Summary

• Monitors single power supply rail with factory-programmed threshold
• Provides active-low reset signal with defined delay characteristics
• Includes manual reset input pin for external system control
• Operates at low supply voltages with minimal quiescent current

Supervisors Applications

• Personal computer systems monitoring multiple voltage rails
• Portable electronic devices requiring low power supervision
• Embedded systems needing reliable power-on reset sequences
• Industrial equipment operating in extended temperature ranges

Supervisors Procurement Notes

Verify the specific suffix D2 corresponds to the 3.0V threshold variant when sourcing. Confirm RoHS compliance status indicated by the plus sign. Ensure the SOT-23-5 package matches your PCB footprint requirements. Check manufacturer datasheets for latest revision updates regarding electrical characteristics and mechanical dimensions before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a fixed 3.0V threshold is required for system supervision. Consider the active-low push-pull output capability for direct interfacing with logic inputs. Evaluate the manual reset feature if external reset control is necessary. Compare against other MAX6306 variants if different threshold voltages or output types are needed for the specific application design constraints.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input programmable reset ICs manufactured by Maxim Integrated, now part of Analog Devices. These circuits are designed to monitor more than one power supply and assert a system reset if any monitored supply falls outside the programmed threshold. The family is known for low supply current and small package size, making them ideal for portable applications.

Supervisors Replacement Considerations

Direct substitutes include other MAX6306 variants with different threshold voltages such as MAX6306UK27D2+T (2.7V) or MAX6306UK31D2+T (3.1V). Cross-reference with MAX6306UK30D1+T if open-drain output is acceptable instead of push-pull. Verify package compatibility and electrical specifications before substitution.
