Maxim Integrated MAX6387XS29D2+T Voltage Supervisor IC

The MAX6387XS29D2+T from Maxim Integrated is a highly reliable and precise voltage supervisor IC designed to monitor power supplies in digital systems. It ensures that the system microprocessor, FPGA, or other digital logic operates at the correct voltage level, enhancing system stability and reliability. This particular model is part of Maxim's extensive family of supervisory circuits that provide a range of voltage threshold options and output configurations.

The MAX6387XS29D2+T operates with a nominal threshold voltage of 2.9V, making it suitable for 3.3V powered systems that require a tight monitoring window to maintain proper functionality. This voltage supervisor features an active-low, push-pull reset output. The push-pull configuration eliminates the need for an external pull-up resistor and ensures a fast and assertive transition to the reset state when the monitored voltage drops below the threshold.

This device comes in a compact, surface-mount 4-pin SC70 package, which is highly space-efficient, making it an excellent choice for space-constrained applications. The small footprint of the MAX6387XS29D2+T allows designers to incorporate voltage monitoring capabilities into their designs without significantly impacting the overall board size.

Additionally, the MAX6387XS29D2+T features a low supply current draw, typically around 1.2µA, which is beneficial for battery-powered and energy-sensitive applications. It also includes an immunity to short voltage transients, which helps to prevent false resets due to noise and other temporary disturbances in the power supply.

One of the key advantages of the MAX6387XS29D2+T is its factory-trimmed reset threshold voltage, which offers high accuracy without the need for external adjustments. This precision ensures that the device will consistently perform as expected, providing a reliable reset signal whenever the monitored voltage falls out of the acceptable range.

The MAX6387XS29D2+T is commonly used in a variety of applications, including portable devices, embedded systems, and industrial equipment. Its robust design and precise voltage monitoring capabilities make it an essential component for any system that requires dependable voltage supervision to protect against improper operation or potential damage due to power supply issues.
