MAX6306EUK25D1+

Supervisors Overview

The MAX6306EUK25D1+ is a CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It features a fixed reset threshold voltage of 2.5V and includes a manual reset input for system control. The device operates within a supply voltage range of 1.2V to 5.5V and draws a low quiescent current of 15µA. It provides an active-low, open-drain reset output with a typical delay of 200ms. The component is housed in a compact SOT-23-5 package and supports operation across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors power supply voltage levels and asserts a reset signal when the supply falls below the programmed threshold.
• Includes a dedicated manual reset input pin allowing external control over the system reset state.
• Designed to ignore fast transients on monitored supplies to prevent false reset assertions during normal operation.

Supervisors Applications

• Monitoring multiple power supplies in personal computer systems
• Portable applications requiring low supply current and small package size
• Battery-powered devices needing reliable voltage supervision

Supervisors Procurement Notes

Verify the exact suffix 'EUK25D1+' against the manufacturer's official datasheet to confirm the specific 2.5V threshold voltage and package variant. Ensure the ordering information matches the required reset polarity and manual reset functionality. Cross-reference the RoHS compliance status and lead-free specifications with the latest product documentation before procurement.

Supervisors Selection Notes

Select this component when a fixed 2.5V reset threshold is required for monitoring lower voltage rails. Consider the 15µA quiescent current for battery life optimization. Verify that the SOT-23-5 package fits the PCB layout constraints. Confirm compatibility with the system's manual reset logic requirements and operating temperature range.

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 and assert a system reset if any monitored supply falls outside the programmed threshold. The family is characterized by low supply current and small package options suitable for portable applications.

Supervisors Replacement Considerations

Check the MAX6306EUK27D1+ or MAX6306EUK30D1+ for different fixed threshold voltages within the same series. Verify functional compatibility regarding reset delay times and manual reset inputs. Ensure the replacement part maintains the same SOT-23-5 package and electrical characteristics for direct substitution.
