MAX6315US28D3+T

Supervisors Overview

The MAX6315US28D3+T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 2.80 V with an accuracy of 1.8%. The device provides an active low, open-drain output signal and includes manual reset functionality without a watchdog timer or battery backup switch. It has a reset delay time of 200 ms and consumes a typical operating current of 5 uA. The component is housed in a SOT-143-4 package and supports surface mount installation. It functions reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides precise voltage supervision with a fixed 2.80 V threshold and high accuracy for reliable system monitoring
• Features an active low open-drain output compatible with various logic families for flexible interface integration
• Includes manual reset capability allowing user-initiated system recovery independent of voltage conditions

Supervisors Applications

• Microprocessor reset circuits requiring stable power monitoring
• Battery-powered systems needing low quiescent current supervision
• Industrial control boards operating in extended temperature environments

Supervisors Procurement Notes

Verify the exact suffix D3+T against official Analog Devices documentation to confirm lead-free status and tape-and-reel packaging specifications. Ensure the ordering part number matches the specific threshold voltage variant required for your design. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance details and recommended soldering profiles. Confirm availability through authorized distributors as stock levels may vary by region.

Supervisors Selection Notes

Select this component when a fixed 2.80 V threshold is required for single-channel voltage monitoring. Consider the 5 uA operating current for applications prioritizing energy efficiency. Verify that the open-drain output type aligns with the pull-up requirements of your target logic interface. Ensure the SOT-143-4 package fits within the available PCB footprint constraints.

Supervisors Part Context

This part belongs to the MAX6315 series of ultra-low power reset circuits designed for microprocessor systems. It shares the same package and general architecture with other variants in the family, differing primarily in threshold voltage settings. The series is characterized by its small form factor and low standby current, making it suitable for space-constrained portable electronics.

Supervisors Replacement Considerations

Compatible substitutes include other MAX6315 variants with different threshold voltages if the voltage level can be adjusted in the design. Direct replacements must maintain the SOT-143-4 package and open-drain output configuration. Verify thermal performance and electrical characteristics match the original specifications before substitution.
