MAX6315US26D3+T

Supervisors Overview

The MAX6315US26D3+T is a voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It features a single monitored input with an active low, open-drain output type and manual reset capability. The device operates within a supply voltage range up to 5.5 V and has a threshold voltage of 3.08 V. Key electrical parameters include a reset delay time of 200 ms, an accuracy of 1.8%, and a working power supply current of 5 uA. The maximum power dissipation is 320 mW.

Supervisors Feature Summary

• Provides system reset functionality via an open-drain output when the monitored supply falls below the programmed threshold.
• Includes a manual reset input for user-initiated system control.
• Designed with low supply current consumption suitable for portable applications.

Supervisors Applications

• Monitoring power supplies in personal computer systems
• Portable electronic devices requiring low power supervision
• Battery-powered equipment needing voltage oversight

Supervisors Procurement Notes

Verify the specific suffix D3+T against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the SOT-143-4 package dimensions align with your PCB footprint. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is appropriate for the target supply rail. Consider the 200 ms reset timeout duration to ensure compatibility with the microprocessor startup sequence. Evaluate the 5 uA quiescent current against battery life requirements. Verify that the open-drain output configuration suits the logic levels of the connected system components.

Supervisors Part Context

This part belongs to the MAX6315 series of microprocessor supervisory circuits. These devices are designed to monitor power-supply voltages and assert a reset signal when necessary. The series offers various threshold voltages and packages to accommodate different application needs while maintaining low power consumption.

Supervisors Replacement Considerations

Check for MAX6315 variants with different threshold voltages or package options if the 3.08 V setting does not fit. Verify compatibility with other MAX63xx series parts from Analog Devices/Maxim Integrated that share similar pinouts and functionalities.
