MAX6339CUT-T

Overview

The MAX6339CUT-T is a quad voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors four independent power supply rails using a BICMOS technology in a compact SOT-23-6 (PDSO6) surface-mount package. The device provides active-low open-drain or open-collector reset outputs for each monitored channel, ensuring system integrity during voltage anomalies. It operates within a supply voltage range of 1 V to 5.5 V and supports an extended industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Monitors four independent voltage inputs simultaneously
• Provides individual active-low reset signals per channel
• Utilizes low-power BICMOS technology for efficient operation
• Available in a space-saving six-pin surface-mount package

Applications

• Multi-rail power supply monitoring in embedded systems
• Voltage supervision for portable electronic devices
• Industrial control unit power integrity verification
• Communication equipment power rail tracking

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure correct threshold voltages and output types. Confirm RoHS compliance status as indicated in manufacturer documentation. Check availability through authorized distributors, as stock levels may vary. Ensure the ordering part number matches the required package variant and temperature grade for your application design.

Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required in a minimal footprint. Consider the BICMOS process for stable performance across the specified temperature range. Verify that the open-drain/open-collector output type aligns with the pull-up requirements of the connected microcontroller or logic interface. Ensure the operating voltage range covers all monitored supply rails.
