MAX6315US30D2-T

Supervisors Overview

The MAX6315US30D2-T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 3.05 V. The device provides an active low, open-drain output with a reset delay time of 200 ms. It supports manual reset functionality and lacks watchdog or battery backup switches. Operating temperatures span from -40°C to +125°C with an accuracy of 1.8%. The component consumes 5 µA of working current and dissipates 320 mW of power. It is housed in a SOT-143-4 surface-mount package.

Supervisors Feature Summary

• Provides precise voltage monitoring with a fixed threshold for reliable system supervision
• Features an active low open-drain output compatible with various logic families
• Includes manual reset capability for controlled system recovery operations

Supervisors Applications

• Portable equipment requiring low-power voltage supervision
• Battery-powered systems needing accurate threshold detection
• Microcontroller reset circuits in industrial environments

Supervisors Procurement Notes

Verify the exact suffix D2 against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the SOT-143-4 package matches your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet before integration. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 3.05 V threshold is required for single-channel supervision. Consider the 5 µA quiescent current for battery-sensitive designs. The open-drain output allows flexible pull-up voltage selection. Verify that the 200 ms reset delay meets your system startup timing constraints. Ensure the operating temperature range covers your application environment.

Supervisors Part Context

This part belongs to the MAX6315 series of ultra-low-power supervisors. The series offers multiple threshold options and package variants. The US30 designation indicates the specific 3.05 V threshold version. The D2 suffix typically denotes the SOT-143-4 package configuration. This family is designed for cost-sensitive applications requiring reliable power management.

Supervisors Replacement Considerations

Check MAX6315US30D2+T for lead-free variant availability. Verify MAX6315US30D3-T if different packaging is needed. Compare MAX6315US31D2-T only if a 3.08 V threshold is acceptable. Ensure any substitute maintains the same open-drain output type and reset delay specifications.
