MAX6333UR20D3

Overview

The MAX6333UR20D3+T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 2.0 V. The device provides one monitored input with an active low, push-pull output type. It includes a reset delay time of 40 ms and consumes a typical operating supply current of 3.3 uA. The component supports overvoltage detection with a threshold of 2.44 V and has a power dissipation rating of 320 mW. It is housed in a SOT-23-3 package suitable for surface mount installation and functions across a temperature range from -40°C to +125°C.

Feature Summary

• Provides simple power supply supervision with active low push-pull output
• Features ultra-low quiescent current consumption for battery-powered applications
• Includes internal reset timer delay to ensure stable power-up sequencing

Applications

• Microprocessor system monitoring
• Portable electronic devices requiring low power standby
• Battery-operated equipment supervision

Procurement Notes

Verify the exact suffix and tape/reel specifications against the manufacturer's latest datasheet before ordering. Confirm RoHS compliance status and lead times directly with authorized distributors as availability may vary. Ensure the selected variant matches the required threshold voltage and package type for your specific design implementation.

Selection Notes

Select this component when a single-channel supervisor with low current draw is required. Compare the 2.0 V threshold against system rail voltages to ensure proper triggering. Consider the SOT-23-3 footprint constraints and thermal dissipation limits relative to your PCB layout and ambient operating conditions.

Part Context

This part belongs to the MAX6333 series of microprocessor supervisors designed for compact, low-power applications. The series offers various threshold options and packaging styles to accommodate different voltage rails and board space requirements while maintaining high accuracy and reliability standards.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family or cross-reference with other manufacturers offering similar threshold voltages and package types. Verify electrical parameter compatibility including reset delay and quiescent current before substitution.
