MAX6338JUB+

Overview

The MAX6338JUB+ is a quad voltage monitor manufactured by Analog Devices Inc./Maxim Integrated. It monitors four supply voltages without external components, featuring factory-trimmed thresholds for +5.0V, +3.3V, +3.0V, +2.5V, +1.8V, and -5.0V inputs. The device includes an adjustable high-input impedance comparator option. It operates within a temperature range of -40°C to +85°C and utilizes a 10-uMAX/uSOP package.

Feature Summary

• Monitors up to four power supplies simultaneously without requiring external components
• Offers factory-trimmed threshold voltages optimized for specific standard supply rails
• Includes an adjustable high-input impedance comparator for general-purpose monitoring

Applications

• Multi-rail power system supervision in embedded systems
• Monitoring critical voltage levels in industrial control equipment
• Power integrity verification in telecommunications infrastructure

Procurement Notes

Verify the exact threshold voltage configuration required for your application, as the MAX6338 series offers multiple variants with different factory-set values. Confirm the package type matches your PCB footprint requirements. Ensure compatibility with your system's operating temperature range. Check for RoHS compliance status if mandated by your project specifications.

Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is necessary. Consider the available factory-trimmed options for standard voltages like 5V or 3.3V to simplify design. The adjustable comparator feature provides flexibility for non-standard voltage monitoring needs. Evaluate the package size constraints against the available 10-pin uMAX form factor.

Part Context

This part belongs to the MAX6338 family of quad voltage monitors designed for compact power management solutions. The series allows for monitoring multiple supplies in space-constrained applications. Maxim Integrated, now part of Analog Devices, developed these devices to provide reliable supervision without complex external circuitry.

Replacement Considerations

Direct substitutes include other MAX6338 variants with different threshold configurations, such as MAX6338OUB+ or MAX6338MUB+. Verify that any replacement maintains the same quad-monitoring capability and compatible package dimensions.
