Product Overview: MAX6315US29D3+T from Maxim Integrated

The MAX6315US29D3+T is a highly reliable, low-power microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant level of system reliability through its reset function, which ensures that the µP starts up in a known state every time power is applied.

This compact device is particularly well-suited for battery-powered applications due to its low power consumption. The MAX6315US29D3+T is available in a small, 4-pin SOT-143 package, making it an ideal choice for space-constrained applications that require a high level of precision and reliability.

Key Features

• Precision Voltage Monitoring: The MAX6315US29D3+T is designed to monitor a preset threshold voltage of 2.93V, ensuring that the system has a stable power supply for proper operation.
• Low Power Consumption: This device is optimized for low-power operations, making it an excellent choice for portable and battery-powered applications.
• Reset Output: The supervisory circuit generates a reset signal whenever the monitored voltage drops below the threshold, maintaining system integrity by resetting the µP.
• Manual Reset Input: A manual reset input is provided, allowing the user to trigger a reset whenever necessary.
• High Accuracy: The MAX6315US29D3+T offers high threshold accuracy (±1.5% over temperature), which is crucial for reliable system operation.
• Immunity to Short VCC Transients: The device is designed to ignore short transients on the VCC line, which helps to prevent false resets.
