MAX6336US20D3+T

Overview

The MAX6336US20D3+T is a supervisory circuit designed for ultra-low-voltage microprocessor systems. It features a fixed reset threshold voltage of 2.0V, ensuring reliable monitoring within the 1.8V to 3.3V operating range. The device operates with low power consumption and includes a manual reset input for system control. It utilizes a push-pull active-low output configuration and is housed in a compact SOT-143-4 package. The component supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Ultra-low-voltage operation suitable for 1.8V–3.3V digital systems
• Fixed 2.0V reset threshold voltage for precise monitoring
• Manual reset input capability for system intervention
• Push-pull active-low output structure

Applications

• Microprocessor supervisory circuits
• Portable battery-powered devices
• Low-voltage digital systems
• Embedded controller reset management

Procurement Notes

Verify the exact suffix designation (+T) against the manufacturer's current product status, as availability may vary. Confirm that the SOT-143-4 package matches your PCB footprint requirements. Ensure the 2.0V threshold aligns with your specific supply rail monitoring needs. Cross-reference the datasheet revision date to confirm technical specifications have not changed. Validate lead-free compliance if required by your assembly process standards.

Selection Notes

Select this component when a fixed 2.0V threshold is required for 1.8V–3.3V systems. The SOT-143-4 package offers space efficiency for compact designs. Consider the manual reset feature if external system control over the reset state is necessary. Verify that the push-pull output drives the connected load appropriately without additional buffering. Ensure the operating temperature range meets the environmental conditions of the final application.

Part Context

This part belongs to the MAX6336 series of ultra-low-voltage microprocessor reset circuits. The series provides various fixed threshold options to accommodate different supply voltages. The US20 variant specifically targets applications requiring a 2.0V detection level. Analog Devices Inc. (formerly Maxim Integrated) manufactures this line for robust system supervision in portable and embedded electronics.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6336 family with different threshold voltages if the 2.0V setting is unsuitable. Verify that alternative components maintain the same SOT-143-4 package and manual reset functionality. Ensure any replacement supports the required 1.8V–3.3V operating range and industrial temperature specifications.
