MAX6315US30D3-T

Supervisors Overview

The MAX6315US30D3-T is a CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features an active-low open-drain reset output and manual reset input. The device operates within a supply voltage range up to 5.5V, with a threshold voltage of 3.08V and an overvoltage threshold of 3.14V. It provides a fixed reset delay time of 200ms and maintains accuracy of 1.8%. Operating current is 5µA, and it functions across temperatures from -40°C to +125°C in a SOT-143-4 package.

Supervisors Feature Summary

• Provides reliable system reset when monitored supply voltage falls below the specified threshold
• Includes manual reset input for external control of the reset state
• Features low operating current suitable for battery-powered applications
• Offers high accuracy for precise voltage supervision

Supervisors Applications

• Microprocessor (µP) reset circuits
• Digital system power supply monitoring
• Portable electronic devices requiring low standby current

Supervisors Procurement Notes

Verify the exact suffix D3 against official Analog Devices documentation to confirm pinout and electrical characteristics match your design requirements. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents before integration into production.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with manual reset capability is required. Ensure the 3.08V threshold aligns with the target supply rail. Consider the SOT-143-4 package size constraints and the -40°C to +125°C temperature range suitability for the intended environment.

Supervisors Part Context

This part belongs to the MAX6315 series of uP reset circuits from Maxim Integrated, now part of Analog Devices. The series offers various threshold voltages and packages. The US30 variant specifically targets 3.3V systems with a 3.08V threshold, providing a standard solution for general-purpose digital logic supervision.

Supervisors Replacement Considerations

Check for MAX6315US30D1+T if a different reset delay time is acceptable. Verify compatibility with MAX6315US31D3+T only if the higher 3.08V threshold variation is permissible. Cross-reference package markings and electrical specs with the original datasheet.
