MAX6315US28D2+T

Supervisors Overview

The MAX6315US28D2+T is a low-power CMOS microprocessor 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 fixed reset threshold voltage of 2.83 V. The device provides an active-low, open-drain output and includes a manual reset input. It offers a typical reset timeout period of 280 ms and functions reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides system reset when supply voltage drops below the preset threshold or upon manual assertion
• Features an open-drain output compatible with various logic families
• Includes a debounced manual reset input for user-initiated system resets

Supervisors Applications

• Microprocessor power supply monitoring in digital systems
• Portable battery-powered equipment requiring low quiescent current
• Embedded controller supervision in industrial applications

Supervisors Procurement Notes

Verify the specific suffix D2 against official datasheets to confirm the exact threshold voltage and package variant. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference the manufacturer's latest documentation for any pinout or electrical characteristic updates prior to finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a fixed threshold near 2.8 V is required for 3.3 V or similar logic systems. The open-drain output allows for wired-OR configurations. Consider the manual reset feature if external user intervention capabilities are necessary for the design. Verify that the SOT-143 package fits the available PCB real estate constraints.

Supervisors Part Context

This part belongs to the MAX6315 family of ultra-low-power reset circuits designed for microprocessor applications. These devices eliminate the need for external components typically used in power-supply monitoring circuits. The series is characterized by low supply current and high accuracy, making it suitable for space-constrained and battery-operated designs.

Supervisors Replacement Considerations

Check for MAX6315 variants with different threshold voltages (e.g., US29, US30) if the 2.83 V threshold does not match the target supply rail. Verify compatibility with alternative manufacturers' single-channel open-drain supervisors in the SOT-143 package.
