Maxim Integrated MAX6382XR26D3+T Microprocessor Reset Circuit

The Maxim Integrated MAX6382XR26D3+T is a high-quality microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a high level of system reliability and accuracy required in critical electronic devices. This tiny, low-power device is ideal for portable and space-constrained applications due to its small size and efficiency.

The MAX6382XR26D3+T offers a precise monitoring system for the power supply, ensuring that the µP is reset to a known state during a power failure. With a factory-set reset threshold voltage of 2.63V, it actively monitors the VCC line for under-voltage conditions. Upon detecting a voltage drop below the threshold, the reset output is driven active, thus safeguarding the µP and associated circuitry from unpredictable behavior.

This device features a reset timeout of 200ms (min), which ensures that the system has adequate time to stabilize before the µP starts operating again after a reset. The active-low, open-drain reset output configuration of the MAX6382XR26D3+T allows for simple interfacing with other components in the system. Additionally, the low supply current of 1.5µA (typ) makes this circuit an energy-efficient option for battery-powered applications.

One of the key advantages of the MAX6382XR26D3+T is its operating temperature range of -40°C to +125°C, which allows for reliable operation in extreme environments. This makes it suitable for automotive, industrial, and other applications where temperature conditions can be harsh.

The device is provided in a compact, 3-pin SC70 package, which is lead-free and RoHS compliant, ensuring that it meets current environmental standards for electronic components. The MAX6382XR26D3+T is also available in tape and reel form, denoted by the "+T" suffix, facilitating easy integration into automated manufacturing processes.

In summary, the Maxim Integrated MAX6382XR26D3+T is a robust and reliable solution for system power monitoring, offering precision, low power consumption, and a small form factor, making it an excellent choice for modern electronic designs.
