MAX6315US46D1+T

Supervisors Overview

The MAX6315US46D1+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.0V to 5.5V and features a fixed threshold voltage of 4.63V. The device provides an open-drain or open-collector reset output with a typical reset delay of 200ms. It functions across an industrial temperature range from -40°C to +125°C and is housed in a compact SOT-143-4 package.

Supervisors Feature Summary

• Provides reliable system supervision through a fixed voltage threshold monitoring mechanism
• Offers flexible output configuration supporting both open-drain and open-collector logic states
• Ensures stable operation under varying thermal conditions across the extended industrial temperature range

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Battery-powered portable devices requiring low standby current
• Industrial control units needing wide temperature stability

Supervisors Procurement Notes

Verify the component authenticity by checking for the Maxim Integrated or Analog Devices branding on the package. Confirm the marking code matches the specific suffix D1+T to ensure the correct 4.63V threshold voltage. Ensure the package type is SOT-143-4 and verify lead-free compliance status as indicated by the plus sign in the part number.

Supervisors Selection Notes

Select this component when a fixed voltage threshold near 4.63V is required for system supervision. It is suitable for applications where open-drain or open-collector outputs are preferred for interfacing with various logic families. Consider the SOT-143-4 package size constraints and the operating temperature range requirements before finalizing the design.

Supervisors Part Context

This part belongs to the MAX6315 family of microprocessor reset circuits designed for low-power applications. The family offers various fixed voltage thresholds and adjustable options to suit different supply rail requirements. The US suffix indicates the SOT-143-4 package, while the D1 suffix specifies the 4.63V threshold voltage variant within the series.

Supervisors Replacement Considerations

Direct substitutes include other MAX6315 variants with compatible thresholds such as MAX6315US45D1+T or MAX6315US50D1+T, provided the voltage level meets the application needs. Cross-referencing with similar open-drain supervisor ICs from other manufacturers requires verifying pin compatibility and electrical specifications.
