MAX6339GUT+T

Overview

The MAX6339GUT+T is a precision quad voltage monitor with microprocessor supervisory reset timing, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2V to 5.5V and features four independent voltage monitoring channels with thresholds at 1.58V, 2.63V, 4.38V, and an adjustable setting. The device provides an active-low open-drain reset output with a fixed 200ms reset delay time. It is housed in a compact SOT-23-6 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent voltage monitoring channels for comprehensive power system supervision
• Provides precise threshold detection including three fixed levels and one fully adjustable channel
• Generates a synchronized active-low reset signal with a guaranteed 200ms delay upon fault detection

Applications

• Multi-rail embedded systems requiring simultaneous voltage supervision
• Microprocessor-based designs needing reliable power-on reset sequencing
• Industrial control units operating in extended temperature environments

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct threshold settings. Confirm RoHS compliance status as indicated in manufacturer documentation. Check current availability through authorized distributors, as stock levels may vary. Ensure the SOT-23-6 footprint matches your PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when multiple voltage rails require individual monitoring within a single IC. The adjustable threshold allows customization for non-standard supply voltages. Consider the low quiescent current for battery-powered applications. Verify that the open-drain output interface is compatible with the downstream logic levels of your microprocessor or controller.

Part Context

This part belongs to the MAX6339 family of quad voltage supervisors designed for robust system management. It complements other Maxim Integrated monitoring solutions by offering multi-channel capability in a small form factor. The series supports various industrial and commercial applications where space constraints and monitoring accuracy are critical design parameters.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6339 series with different threshold configurations. Verify functional equivalence if substituting with other quad voltage monitors from Analog Devices. Ensure package compatibility and electrical specifications match the original design requirements.
