Maxim Integrated MAX6315US48D2+T Microprocessor Reset Circuit

The MAX6315US48D2+T is a compact, high-precision microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a robust set of features to ensure that the µP resets to a known state during power-up, power-down, or brown-out conditions. The device is particularly suitable for portable, battery-operated applications due to its low power consumption and small footprint.

Key Features

• Reset Threshold Voltage: The MAX6315US48D2+T has a preset reset threshold voltage of 4.8V, suitable for 5V-powered systems.
• Temperature Range: It operates over an extended industrial temperature range, making it reliable for various challenging environments.
• Reset Output: The reset output is active-low and is guaranteed to be in the correct state for V<sub>CC down to 1V.
• Low Power Consumption: With its low supply current of 1µA (typical), it is an excellent choice for power-sensitive applications.
• High Accuracy: Reset threshold accuracy is maintained at ±2.5% over temperature, ensuring reliable monitoring of the system voltage.
• Immune to Short V<sub>CC Transients: The device is designed to ignore fast transients on the V<sub>CC line, preventing false resets.
• Packaging: It comes in a compact SOT-143 package, which is ideal for space-constrained applications.
