MAX6315US44D2-T

Supervisors Overview

The MAX6315US44D2-T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in µP and digital systems. It features a fixed threshold voltage of 4.39 V for the monitored input. The device provides an active-low, open-drain reset output with a manual reset capability. It operates within a supply voltage range up to 5.5 V and maintains accuracy of 1.8%. The component supports a reset delay time of 200 ms and functions at temperatures from -40°C to +125°C. It consumes 5 µA of operating current and is housed in a SOT-143-4 package.

Supervisors Feature Summary

• Monitors single-channel power supply voltages for microprocessor and digital system reliability
• Provides active-low open-drain reset signal with manual reset functionality
• Operates with ultra-low quiescent current consumption for power-sensitive applications

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system voltage supervision
• Battery-powered device power management

Supervisors Procurement Notes

Verify RoHS compliance status carefully as some listings indicate non-compliance. Confirm lead-free status and manufacturer lot codes. Check for obsolescence or end-of-life notices from Analog Devices/Maxim Integrated. Ensure the specific suffix matches the required threshold voltage and package type for your design requirements.

Supervisors Selection Notes

Select this part when a fixed 4.39 V threshold is required for single-supervision tasks. Consider the SOT-143-4 package size constraints. Evaluate the 200 ms reset delay against system startup timing needs. Verify compatibility with the target logic levels due to the open-drain output configuration requiring external pull-up resistors.

Supervisors Part Context

This component belongs to the MAX6315 series of uP reset circuits. It is manufactured by Analog Devices Inc., formerly Maxim Integrated. The series offers various threshold voltages and package options to suit different embedded system monitoring requirements. It serves as a dedicated voltage supervisor for ensuring stable operation of digital logic.

Supervisors Replacement Considerations

Check for MAX6315US44D2+T which may have updated RoHS compliance. Other MAX6315 variants with similar thresholds can be considered if pinout and electrical characteristics match exactly.
