MAX6315US31D2

Supervisors Overview

The MAX6315US31D2 is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for monitoring single power supply rails. It operates within a maximum supply voltage of 5.5 V and features an active low, open-drain output type. The device includes a manual reset input capability and lacks a watchdog timer or battery backup switch functionality. Key electrical parameters include a threshold voltage of 3 V, an overvoltage threshold of 3.05 V, and a reset delay time of 1.4 ms. It consumes a typical operating supply current of 5 uA and offers accuracy of 1.8%. The component is housed in a SOT-143-4 package, supports surface mount installation, and functions across a temperature range from -40 C to +125 C with a power dissipation rating of 320 mW.

Supervisors Feature Summary

• Provides precise supervision of a single power supply rail with factory-set threshold levels
• Features an active low, open-drain output suitable for interfacing with various logic families
• Includes a manual reset input for system control flexibility
• Designed with low supply current consumption to support portable applications

Supervisors Applications

Supervisors Procurement Notes

Verify the specific suffix D2 against official manufacturer documentation to confirm pinout and electrical characteristics match your design requirements. Check current availability status as components may be subject to limited supply or end-of-life notices. Ensure compatibility with your PCB footprint and thermal management strategy before finalizing procurement decisions.

Supervisors Selection Notes

Choose this component when a single-channel supervisor with open-drain output is required. Consider the 1.4 ms reset delay and 3 V threshold for appropriate timing and voltage levels. Evaluate the wide operating temperature range for environmental suitability. Compare against other MAX631x variants if different output types or thresholds are needed.

Supervisors Part Context

This part belongs to the MAX631x series of CMOS microprocessor supervisory circuits. These devices are engineered to monitor power supplies and assert a reset signal when voltages fall outside specified limits. The series typically offers low power consumption and small package options, making them suitable for space-constrained and battery-operated applications requiring reliable voltage monitoring.

Supervisors Replacement Considerations

Consult official substitution guides for compatible parts within the MAX631x family. Verify that alternative candidates match the SOT-143-4 package, 3 V threshold, and open-drain output configuration. Cross-reference datasheets to ensure equivalent electrical performance and pin compatibility.
