MAX6334UR16D3

Supervisors Overview

The MAX6334UR16D3 is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 0.8V to 5.5V and features an active-low, open-drain reset output with a fixed 40ms timeout delay. The device monitors a single input line and triggers a reset when the voltage falls below the specified threshold of 1.6V. Designed for surface-mount installation in SOT-23-3 packages, it draws a typical quiescent current of 3.3µA. The component supports operation across an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable system reset generation via active-low open-drain output
• Ensures stable power-up sequencing with fixed 40ms reset timeout delay
• Enables low-power operation through ultra-low 3.3µA quiescent current consumption

Supervisors Applications

• Microprocessor and microcontroller power supply monitoring
• Battery-powered portable electronic devices requiring low standby current
• Industrial control systems operating in extended temperature environments

Supervisors Procurement Notes

Verify exact availability status as distribution channels may report limited stock or discontinuation. Confirm RoHS compliance documentation matches specific manufacturing dates. Ensure ordering suffixes align with required packaging formats such as cut tape or reel quantities. Cross-reference datasheet revisions to confirm pinout and electrical parameter consistency before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel supervisor with open-drain output is required. Verify that the 1.6V threshold matches the monitored rail's minimum operating voltage. Consider the 40ms timeout duration against system startup requirements. Evaluate package compatibility with existing PCB footprint constraints. Compare quiescent current specifications against total system power budgets.
