MAX6339FUT+T

Overview

The MAX6339FUT+T is a precision quad voltage monitor with microprocessor supervisory reset timing. It monitors up to four system supply voltages using an active low, open drain or open collector output. The device operates within a power supply range of 1V to 5.5V and features a minimum reset timeout of 140ms. It is housed in a SOT-23-6 package and supports surface mount installation.

Feature Summary

• Monitors up to four independent system supply voltages simultaneously
• Provides precise microprocessor supervisory reset timing
• Features active low output with open drain or open collector configuration

Applications

• Microprocessor system power supervision
• Multi-voltage monitoring in embedded systems
• Battery-powered device voltage tracking

Procurement Notes

Verify the specific threshold voltage configuration for the FUT suffix against the official datasheet, as this variant may differ from other MAX6339 subtypes. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies by region. Ensure the SOT-23-6 package footprint matches your PCB design requirements before ordering.

Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required. The open-drain output allows for flexible interfacing with various logic levels. Consider the 140ms minimum reset delay for system startup stability. Verify that the operating temperature range meets your environmental specifications.

Part Context

This part belongs to the MAX6339 series of quad voltage supervisors from Analog Devices/Maxim Integrated. The series offers various threshold options and package types to suit different multi-rail monitoring needs. The MAX6339 family is designed for cost-effective and space-constrained applications requiring reliable power management.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6339 family with matching threshold voltages. Verify electrical characteristics such as reset delay and quiescent current if substituting with other quad supervisor ICs.
