MAX6338KUB-T

Overview

The MAX6338KUB-T is a quad voltage monitor IC from Analog Devices Inc./Maxim Integrated, designed for robust power-system supervision in safety-critical automotive applications. It features four independent monitoring channels with open-drain or open-collector active-low outputs. The device operates within a supply voltage range up to 5.5 V and includes specific threshold voltages of 2.19 V, 2.93 V, and two adjustable inputs. It offers a minimum reset timeout of less than 1 ms and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides simultaneous supervision of four distinct voltage rails using dedicated monitoring channels.
• Features open-drain or open-collector outputs compatible with various logic families for flexible system integration.
• Includes adjustable threshold inputs allowing customization of monitoring levels for specific application requirements.

Applications

• Safety-critical automotive electronic systems
• Multi-rail power distribution networks
• Embedded controller voltage supervision

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist within the MAX6338 family. Confirm availability status directly with authorized distributors, as supply constraints may apply. Ensure the selected variant matches the required threshold specifications and package type for your design. Cross-reference part numbers carefully to avoid confusion between similar supervisory circuits.

Selection Notes

Select this component when multi-voltage monitoring is required in compact surface-mount packages. The adjustable thresholds provide flexibility for non-standard voltage rails. Consider the open-drain output structure for level shifting needs. Verify that the operating temperature range meets environmental requirements. Compare pinout compatibility if replacing existing designs.

Part Context

This part belongs to the MAX6338 series of quad voltage monitors, which are widely used in industrial and automotive sectors. The KUB-T suffix indicates a specific threshold configuration and tape-and-reel packaging. These devices complement other Maxim Integrated supervisory solutions by offering high channel density in small form factors.

Replacement Considerations

Check for direct substitutes within the MAX6338 family with different threshold combinations. Verify pin-to-pin compatibility before substitution. Ensure equivalent electrical characteristics such as reset timeout and supply current are maintained. Consult manufacturer cross-reference guides for validated alternatives.
