MAX6339OUT

Overview

The MAX6339OUT is a precision quad voltage monitor featuring microprocessor supervisory reset timing. It monitors up to four system supply voltages without external components, utilizing factory-set thresholds ranging from 1.1V to 5V. The device operates within a supply voltage range of 1V to 5.5V and draws 55µA. It provides active low open-drain outputs with a 200ms reset delay. Accuracy is specified at 5%, and it functions between -40°C and +85°C in a SOT-23-6 package.

Feature Summary

• Monitors up to four independent system supply voltages simultaneously
• Provides precise supervisory reset timing for microprocessor applications
• Delivers active low open-drain output signals
• Operates with low quiescent current consumption

Applications

• Safety-critical automotive power system supervision
• Microprocessor reset circuitry
• Multi-rail power monitoring systems

Procurement Notes

Verify the specific suffix (e.g., OUT) against the official Analog Devices datasheet to confirm threshold configurations and package type. Ensure RoHS compliance status matches project requirements. Confirm availability through authorized distributors as stock levels vary. Validate that the operating temperature range meets environmental specifications.

Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required. The fixed factory-set thresholds simplify design compared to adjustable variants. Ensure the input voltage range aligns with the 1.1V to 5V monitoring capability. Consider the SOT-23-6 footprint constraints during PCB layout.

Part Context

Part of the MAX6339 family of quad voltage supervisors. Designed for applications requiring reliable power management without complex external circuitry. Offers a compact solution for embedded systems needing multi-voltage oversight.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX633x series. Verify threshold voltage compatibility if substituting with other quad monitors. Ensure package dimensions match the SOT-23-6 form factor.
