Maxim Integrated MAX6315US26D2+T Low-Power Microprocessor Reset Circuit

The MAX6315US26D2+T is a compact, highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. Manufactured by Maxim Integrated, a renowned leader in analog and mixed-signal engineering, this device ensures that your microprocessor, microcontroller, or other digital system remains within safe operating conditions by providing a precise voltage monitoring solution.

This supervisory circuit is specifically designed to maintain system integrity by asserting a reset signal whenever the VCC supply voltage falls below a preset threshold of 2.63V, tailored for 2.6V-powered circuits. The reset output remains asserted for a minimum of 140ms after VCC has risen above the reset voltage threshold, ensuring a proper system reset. This feature provides ample time for the system to stabilize before the processor begins operation, which is crucial for preventing erroneous system behavior.

The MAX6315US26D2+T comes in a space-saving SOT-143 package, making it an ideal choice for applications where board space is at a premium. It is also characterized for operation over a wide temperature range of -40°C to +85°C, which allows for use in various environments and applications.

One of the key advantages of this device is its low power consumption. It draws a quiescent current of only 1µA, making it suitable for battery-operated and portable applications where power efficiency is critical. This feature helps in prolonging battery life and reducing the overall power consumption of the system.

Moreover, the MAX6315US26D2+T offers an active-low RESET output, which is guaranteed to be in the correct state for VCC down to 1V. This ensures the device can handle brown-out conditions effectively, which is essential for applications that may experience dips in power supply levels.

In summary, the Maxim Integrated MAX6315US26D2+T supervisory circuit is a robust solution for safeguarding digital systems against power supply anomalies. With its precise voltage monitoring, low power consumption, and small footprint, it is an excellent choice for a wide range of applications requiring reliable system reset functionality.
