MAX6326UR30+T

Supervisors Overview

The MAX6326UR30+T is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for monitoring single voltage rails. It operates within a supply voltage range of up to 5.5V and features a fixed threshold of 3V. The device provides an active-low, open-drain reset output with a typical reset delay of 185ms. It consumes only 500nA of quiescent current, making it suitable for battery-powered applications. The component is housed in a compact SOT-23-3 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low power consumption of 500nA for extended battery life
• Fixed 3V threshold ensures precise voltage supervision
• Compact SOT-23-3 package minimizes board space
• Active-low open-drain output simplifies interface logic

Supervisors Applications

• Portable consumer electronics requiring low standby current
• Battery-operated instrumentation systems
• Embedded controllers needing reliable power-on reset
• Industrial control units operating in harsh environments

Supervisors Procurement Notes

Verify the exact suffix UR30+T to confirm the 3V threshold and SOT-23-3 packaging. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the open-drain output configuration matches your system's pull-up requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 3V supervision threshold is required without programmability. The ultra-low 500nA current draw makes it ideal for energy-constrained designs compared to higher-current alternatives. Consider the SOT-23-3 footprint constraints during layout planning. Verify that the 185ms reset delay meets the timing requirements of the downstream microcontroller or logic circuits.

Supervisors Part Context

This part belongs to the MAX6326/28/46/48 series of voltage supervisors. These devices are engineered for simple reset generation without complex watchdog or manual reset features. The series offers various threshold voltages and packages, with the MAX6326UR30+T specifically providing the 3V option in a small outline transistor package.

Supervisors Replacement Considerations

Check for other parts in the MAX6326 family with different thresholds or packages. Verify pinout compatibility if substituting with similar supervisory ICs from other manufacturers. Ensure the replacement maintains the same open-drain output type and low quiescent current specifications.
