MAX6338CUB+T

Overview

The MAX6338CUB+T is a quad voltage monitor supervisor circuit manufactured by Analog Devices Inc./Maxim Integrated. It features four independent outputs within a compact 10-uMAX/uSOP package. The device monitors supply voltages with specific threshold levels including 2.93V, 4.38V, and adjustable settings. It operates over an extended temperature range of -40°C to +85°C. The component provides active-low reset signals with a minimum reset timeout of less than 1ms. It supports open-drain or open-collector outputs for flexible system integration.

Feature Summary

• Quad-channel voltage monitoring capability for comprehensive power supervision
• Compact surface-mount packaging suitable for space-constrained designs
• Configurable threshold options including fixed and adjustable voltage levels

Applications

• Multi-rail power supply monitoring in embedded systems
• Voltage supervision for microprocessor and FPGA boards
• Industrial control unit power integrity verification

Procurement Notes

Verify the exact suffix configuration against official datasheets to ensure correct threshold selection and output type compatibility. Confirm availability status as distribution channels may report limited stock or discontinuation notices. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when multiple independent voltage rails require simultaneous supervision within a single integrated solution. The available threshold configurations allow customization for various standard logic levels. Ensure the required operating temperature range aligns with the specified industrial limits. Verify that the open-drain output structure matches the downstream logic interface requirements of the target application design.

Part Context

This part belongs to the MAX6338 series of multi-voltage supervisors designed for robust power management. The series offers various pinout and threshold combinations to accommodate diverse system architectures. Maxim Integrated, now part of Analog Devices, specializes in high-reliability analog and mixed-signal components for critical infrastructure applications.

Replacement Considerations

Direct substitutes include other variants within the MAX6338 family such as MAX6338MUB+ or MAX6338OUB+, which share identical functional characteristics but differ in specific threshold values or package options. Verify electrical compatibility before substitution.
