Overview
The MAX6334UR18D3+T is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 0.7V to 5.5V and features an active-low, open-drain reset output. The device monitors a specific threshold voltage of 1.8V with a typical reset delay time of 100ms. It draws a low operating supply current of 3.3µA and functions reliably across an extended temperature range from -40°C to +125°C. The component is housed in a compact SOT-23-3 surface-mount package.
Feature Summary
- Provides precise monitoring of power supply voltages to ensure system reliability
- Features an active-low open-drain reset output for flexible interfacing
- Designed with ultra-low supply current consumption for battery-powered applications
Applications
- Monitoring power supplies in 1.8V microprocessor systems
- Digital system supervision requiring low-power operation
- Space-critical embedded designs using small packages
Procurement Notes
Verify the exact suffix D3 against the manufacturer's official datasheet to confirm the 1.8V threshold specification. Confirm RoHS compliance status through the latest documentation. Check current availability as distribution channels may vary. Ensure the SOT-23-3 package matches your PCB footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component when an open-drain output is required for wired-OR configurations or level shifting. It is suitable for systems needing a 1.8V threshold with a standard 100ms timeout. Compare against push-pull variants if drive strength is critical. Ensure the 0.7V minimum operating voltage meets your lowest supply rail requirements.
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 precision comparators and timers. The MAX6334 specifically offers an open-drain output, distinguishing it from the push-pull outputs of the MAX6332 and MAX6333 models.
Replacement Considerations
MAX6334UR18D2+T: Verify if the D2 suffix indicates a different tolerance or revision than D3. MAX6333UR18D3+T: Requires circuit modification due to push-pull output versus open-drain.
