Product Overview: MAX6387XS31D3+T from Maxim Integrated

The MAX6387XS31D3+T is a high-quality, precision microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated. This device is engineered to monitor power supplies in digital systems; it provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5V-powered circuits.

The MAX6387XS31D3+T is part of Maxim Integrated's series of supervisory circuits that help to safeguard system integrity by monitoring the power supply voltage levels. This particular model comes with a preset threshold voltage of 3.1V, which is ideal for systems that operate around this voltage level. When the monitored voltage drops below this threshold, the device asserts a reset signal to the µP, ensuring that the system resets cleanly during power-up, power-down, or brownout conditions.

This supervisory IC comes in a compact, 4-pin SC70 package, making it suitable for space-constrained applications. The small size does not compromise its performance, as it provides a reset output signal with an active-low, push-pull configuration. The reset signal from the MAX6387XS31D3+T is guaranteed to be valid down to a VCC of 1.0V, which enhances its reliability in low-voltage conditions.

The MAX6387XS31D3+T also features a low supply current of typically 5.5µA, which is critical for battery-operated devices where power efficiency is paramount. Moreover, it has an operating temperature range of -40°C to +125°C, accommodating a wide variety of environmental conditions.

Maxim Integrated's commitment to quality ensures that the MAX6387XS31D3+T supervisory circuit is a dependable component for any application requiring voltage monitoring. It is commonly used in computers, controllers, intelligent instruments, portable/battery-powered equipment, and other microprocessor-based systems that require precise and reliable monitoring of the power supply voltage.

In summary, the MAX6387XS31D3+T is a versatile, efficient, and reliable solution for power supply monitoring, offering peace of mind for designers and engineers looking to enhance the resilience and performance of their digital systems.
