MAX6315US43D3-T

Supervisors Overview

The MAX6315US43D3-T is a voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1 V to 5.5 V and features a threshold voltage of 4.3 V. The device provides an active low, open-drain reset output with a manual reset capability. It includes a fixed reset delay time of 200 ms and maintains an operating supply current of 5 uA. The component is housed in a compact 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 manual reset functionality for system control
• Features low power consumption suitable for battery applications
• Offers high accuracy voltage monitoring with open-drain output

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing reliable power supervision
• Embedded controllers requiring manual reset inputs

Supervisors Procurement Notes

Verify the specific suffix D3-T for tape and reel packaging configuration. Confirm RoHS compliance status through official documentation. Check current lifecycle status as this series may be subject to discontinuation or limited availability. Ensure the manufacturer designation matches Analog Devices Inc. or Maxim Integrated for authenticity.

Supervisors Selection Notes

Select this component when a 4.3 V threshold is required for single-supervision applications. Choose the open-drain output type if wired-OR logic compatibility is needed. Consider the SOT-143-4 package for space-constrained designs. Verify that the 200 ms delay meets system timing requirements during power-up sequences.

Supervisors Part Context

This part belongs to the MAX6315 series of microprocessor supervisory circuits. These devices are designed to monitor a single power supply rail and generate a reset signal when the voltage drops below the specified threshold. The series is known for its low quiescent current and wide operating temperature range, making it suitable for industrial and consumer electronics.

Supervisors Replacement Considerations

Check for MAX6315US43D3+T as a potential lead-free alternative. Verify pinout compatibility before substitution. Review datasheet differences for any changes in reset delay or accuracy specifications.
