Product Overview: MAX6315US44D1-T from Maxim Integrated

The MAX6315US44D1-T is a compact, high-precision microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require voltage monitoring and battery control functions in their operations.

This device is specifically tailored to maintain system integrity by monitoring the power supply voltage levels. It ensures that the µP and other critical components operate at the correct voltage level, which is crucial for maintaining system stability and performance. The MAX6315US44D1-T asserts a reset signal whenever the VCC supply voltage falls below its preset threshold of 4.4V. The reset output remains asserted for a minimum of 140ms after VCC has risen back above the reset threshold, providing a stable reset deassertion for the µP.

One of the key features of the MAX6315US44D1-T is its low supply current, making it an ideal choice for power-sensitive applications. The device is designed to consume minimal power, which helps in extending battery life in portable applications. Additionally, the MAX6315US44D1-T is available in a compact SOT-143 package, which saves valuable board space and is suitable for space-constrained applications.

The MAX6315US44D1-T is equipped with a debounced manual reset input. This feature allows for a manual override of the automatic reset, providing designers with additional flexibility and control over the reset function. The device also includes an active-low reset output, which is guaranteed to be in the correct state for VCC down to 1V, further ensuring reliable operation under a wide range of power conditions.

Maxim Integrated's MAX6315US44D1-T is designed to meet the stringent requirements of complex digital systems, providing a robust and reliable solution for system monitoring. It is commonly used in applications such as portable/battery-powered equipment, computers, controllers, intelligent instruments, and critical µP power monitoring.

In summary, the MAX6315US44D1-T is a versatile and reliable µP supervisory circuit that provides vital monitoring capabilities, ensuring that digital systems operate within their specified voltage ranges, thereby enhancing system reliability and performance.
