MAX6328UR26+

Supervisors Overview

The MAX6328UR26+T is a single-channel voltage supervisor IC manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5V and features a fixed threshold voltage of 2.6V for power monitoring. The device provides an active-low, open-drain reset output with a minimum reset timeout of 100ms. Designed for surface-mount installation, it is housed in a compact SOT-23-3 package. The component supports a wide operating temperature range from -40°C to +85°C and consumes a typical quiescent current of 500nA, ensuring efficient performance in low-power applications.

Supervisors Feature Summary

• Provides precise power supply monitoring with factory-set threshold accuracy
• Features an active-low open-drain reset output compatible with various logic families
• Ensures stable switching through internal hysteresis mechanisms
• Delivers ultra-low power consumption suitable for battery-operated systems

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Embedded microcontroller system power supervision
• Industrial control units operating in harsh environments
• Communication equipment power integrity monitoring

Supervisors Procurement Notes

Verify the specific suffix designation when ordering, as packaging options such as tape-and-reel or cut tape may vary by distributor. Confirm that the selected variant matches the required threshold voltage and package type for your design. Ensure compliance with RoHS3 standards if environmental regulations apply to your manufacturing process. Cross-reference part numbers carefully to avoid confusion between similar series members.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisory circuit is needed for a single voltage rail. The open-drain output allows for flexible interfacing with different logic levels. Consider the 100ms minimum timeout to ensure adequate delay for power stabilization. Verify that the SOT-23-3 footprint fits your PCB layout constraints and that the thermal characteristics meet your operational requirements.

Supervisors Part Context

This device belongs to the MAX6328U family of ultra-low-power voltage supervisors. It shares functional similarities with other Maxim Integrated reset circuits but is distinguished by its specific 2.6V threshold and open-drain output configuration. The family is designed to replace discrete comparator solutions, reducing board space and assembly costs while improving reliability through integrated hysteresis and precise thresholding.

Supervisors Replacement Considerations

Direct substitutes include the NCP803SN263T1G, which offers a similar 2.63V threshold and SOT-23-3 package. Other alternatives in the MAX6328 series with different thresholds or push-pull outputs may require circuit adjustments. Verify pin compatibility and electrical specifications before swapping components.
