Overview
The MAX6331TUR+ is a precision shunt regulator with an active-high push-pull reset output in a SOT23-3 package. It regulates the shunt voltage to 3.3V with ±1.5% tolerance and monitors input voltage against a 3.06V threshold (±1.5%). The device provides a 140ms reset timeout period without external components, operates from -40°C to +85°C, and supports a shunt current range of 100µA to 50mA.
Feature Summary
- Combines a precision shunt regulator with a power-on reset function in a single compact package
- Provides active-high push-pull reset output for reliable microprocessor supervision
- Offers low-cost operation from high-voltage sources while protecting systems from brownout conditions
Applications
- Controllers
- Household Appliances
- Intelligent Instruments
- Critical µP and µC Power Monitoring
- Portable/Size-Sensitive Equipment
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging and '+' confirms lead-free status per manufacturer standards. Confirm the minimum order increment requirement of 2,500 pieces aligns with procurement constraints. Ensure the selected variant matches the required reset polarity and shunt voltage specifications for the target application design.
Selection Notes
Select this component when board space is limited due to its 3-pin SOT23 form factor. Choose the MAX6331 variant specifically for applications requiring an active-high reset signal. Ensure the system load current remains within the 100µA to 50mA shunt current range to maintain regulation stability and proper reset timing functionality.
Part Context
This part belongs to the MAX6330/MAX6331 family of precision shunt regulators integrated with microprocessor supervisory circuits. The MAX6331 series is distinguished by its active-high reset output, contrasting with the MAX6330's active-low configuration. Both share identical shunt regulation capabilities and package dimensions.
Replacement Considerations
MAX6330TUR+ serves as a functional alternative if an active-low reset output is acceptable. Verify that the replacement maintains the same 3.3V shunt regulation voltage and 3.06V reset threshold to ensure compatibility with existing circuit designs.
