Overview
The MAX6467US29D3+T is a fixed-threshold microprocessor supervisory reset circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single power supply input with a fixed threshold voltage of 2.925V. The device features an active-low, open-drain reset output and supports manual reset functionality. It operates within a supply voltage range up to 5.5V and maintains performance across an extended temperature range from -40°C to +125°C. The component is housed in a compact SOT-143-4 surface-mount package.
Feature Summary
- Provides reliable system reset generation based on a fixed 2.925V monitoring threshold
- Includes manual reset capability for external control or initialization sequences
- Delivers an active-low open-drain reset signal compatible with digital logic interfaces
Applications
- Microprocessor power supply supervision
- Embedded system voltage monitoring
- Portable electronic device power management
Procurement Notes
Verify the specific suffix D3+T indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated to ensure authenticity. Check RoHS compliance status against current regulatory requirements. Validate the SOT-143-4 package marking for identification purposes during assembly inspection.
Selection Notes
Select this component when a fixed 2.925V threshold is required for system supervision. Ensure the application demands an active-low open-drain output configuration. Verify that the operating environment falls within the specified -40°C to +125°C temperature range. Consider the SOT-143-4 footprint constraints for PCB layout compatibility.
Part Context
This part belongs to the MAX6467/MAX6468 family of microprocessor supervisors. These devices are designed to monitor voltage rails in complex digital systems. The US29 variant specifically sets the reset threshold at 2.925V. The T suffix denotes reel packaging for automated assembly processes.
Replacement Considerations
Cross-reference with other MAX6467 variants sharing the same SOT-143-4 package if pinout compatibility is critical. Verify threshold voltage matches the 2.925V requirement before substituting with other series members.
