Overview
The MAX6333UR19D3-T is a 3-pin, ultra-low-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single voltage input with a threshold of 1.9V and features an active-low push-pull output. The device operates within a supply voltage range up to 5.5V and includes a minimum reset timeout period of 100ms. It functions in temperatures from -40°C to +125°C and consumes only 3.3µA of quiescent current. Packaged in SOT-23-3, it eliminates external components for power supply monitoring.
Feature Summary
- Monitors power supply voltages and asserts a reset signal when the supply drops below a preset threshold
- Provides an active-low push-pull RESET output without requiring manual reset or watchdog timer functionality
- Operates with ultra-low quiescent current consumption suitable for battery-powered systems
Applications
- Microprocessor (µP) and digital system power supply monitoring
- Battery-operated electronic devices requiring low-power supervision
- Systems needing automatic reset upon power failure or brown-out conditions
Procurement Notes
Verify the exact suffix D3 corresponds to the 1.9V threshold and 100ms timeout configuration. Confirm RoHS compliance status and lead times directly with authorized distributors as availability varies. Ensure the SOT-23-3 package matches your PCB footprint requirements before ordering.
Selection Notes
Select this component when a fixed 1.9V threshold and push-pull output are required. Compare against MAX6333 variants with different thresholds or open-drain outputs if system logic levels differ. Consider the 100ms minimum timeout duration relative to system startup requirements.
Part Context
Part of the MAX6332/MAX6333/MAX6334 family of 3-pin uPower Reset Circuits. These devices simplify design by integrating voltage monitoring and reset generation into a small package, reducing component count and board space compared to discrete solutions.
Replacement Considerations
MAX6333UR18D3+T offers a 1.8V threshold. MAX6333UR21D3+T provides a 2.1V threshold. MAX6334 series devices feature open-drain outputs instead of push-pull.
