MAX6333UR16D3

Overview

The MAX6333UR16D3 is a low-power voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed reset threshold voltage of 1.6 V. The device provides an active-low, push-pull output with a typical reset delay time of 200 ms. It consumes only 3.3 µA of quiescent current and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a compact SOT-23-3 surface-mount case, it lacks manual reset, watchdog timer, or battery backup switching capabilities.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Compact three-pin surface-mount packaging for space-constrained designs
• Active-low push-pull output driver for direct logic interfacing

Applications

• Portable electronic devices requiring efficient power management
• Embedded microprocessor systems needing reliable power-on reset
• Industrial control units operating in extreme temperature environments

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status via official documentation before integration. Check current lifecycle status as availability may vary by region. Ensure proper handling procedures are followed during storage and assembly to maintain device integrity.

Selection Notes

Select this component when a fixed 1.6 V threshold is required for system monitoring. Consider the SOT-23-3 package constraints for PCB layout planning. Evaluate the 3.3 µA current draw against total system power budgets. Verify that the absence of manual reset and watchdog features aligns with application requirements.

Part Context

This part belongs to the MAX6333 series of uPower Reset Circuits designed for monitoring single voltage rails. It complements other variants in the family offering different threshold voltages and output configurations. The series emphasizes minimal footprint and low standby current for portable applications.

Replacement Considerations

MAX6333UR16D3+T serves as the lead-free equivalent variant. Cross-reference with MAX6333URxxD3+T models for alternative threshold options within the same package.
