MAX6333UR22D3+T

Overview

The MAX6333UR22D3+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.8V to 5.5V and features a fixed reset threshold voltage of 2.2V. The device provides an active-low, push-pull RESET output with a typical timeout period of 100ms. It is designed for low-power applications, consuming only 3.3µA of quiescent current. The component is housed in a compact SOT-23-3 surface-mount package and supports an extended operating temperature range from -40°C to +125°C.

Feature Summary

• Provides reliable system reset when supply voltage drops below the preset threshold
• Features ultra-low power consumption suitable for battery-operated devices
• Includes a fixed timeout period to ensure stable power-up sequencing

Applications

• Microprocessor (µP) and digital system power supply monitoring
• Battery-powered portable electronic devices
• Low-voltage embedded controller systems

Procurement Notes

Verify the exact suffix D3 against official datasheets to confirm the 2.2V threshold and 100ms timeout specifications. Confirm RoHS compliance status and check for obsolescence notices as this series may have limited availability. Ensure the SOT-23-3 footprint matches your PCB design requirements before finalizing procurement.

Selection Notes

Select this component when a fixed 2.2V threshold and push-pull output are required for low-voltage monitoring. Compare the 100ms timeout against system startup requirements. Consider the SOT-23-3 package size constraints and the 3.3µA current draw relative to other options in the MAX6333 family.

Part Context

This part belongs to the MAX6332/MAX6333/MAX6334 family of 3-pin, ultra-low-voltage, low-power µP reset circuits. These devices eliminate external components by integrating precise voltage monitoring and reset generation into a single small package. The MAX6333 variant specifically offers an active-low push-pull output, distinguishing it from the open-drain MAX6334 and active-high MAX6332.
