Maxim Integrated MAX6315US30D4+T Microprocessor Reset Circuit

The MAX6315US30D4+T is a highly compact and reliable microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated. This precision device is engineered to monitor power supplies in µP and digital systems, providing a significant boost in system reliability and performance. It is an ideal solution for managing system resets and ensuring proper operation of applications requiring high accuracy and reliability.

With a fixed-sense threshold voltage of 3.0V, the MAX6315US30D4+T is specifically tailored for monitoring 3.3V power supplies and other voltage sources close to this threshold. This device maintains system integrity by asserting a reset signal whenever the VCC supply voltage falls below the preset threshold. The reset output remains asserted for a period of at least 140ms after VCC has risen above the reset voltage threshold, ensuring the system has sufficient time to stabilize before resuming operation.

The MAX6315US30D4+T comes in a compact SOT-143 package, making it suitable for space-constrained applications. The low supply current of only 1µA (typical) makes it an energy-efficient choice for portable and battery-operated devices. This component is also characterized for operation over a wide temperature range of -40°C to +85°C, ensuring reliable performance in diverse operating environments.

Key features of the MAX6315US30D4+T include:

• Fixed 3.0V ±2% reset threshold voltage
• Low 1µA supply current
• Guaranteed reset valid to VCC = 1V
• Minimum 140ms reset pulse width
• Immune to short VCC transients
• No external components required
• Compact SOT-143 package
• Wide operating temperature range: -40°C to +85°C

The device is also available in a tape-and-reel format under the part number MAX6315US30D4+T, which facilitates automated assembly processes, making it a convenient choice for mass production requirements. Whether it's for computers, controllers, intelligent instruments, critical µP and µC power monitoring, the MAX6315US30D4+T provides a simple and robust solution for system reset management.

Maxim Integrated's commitment to quality and reliability ensures that the MAX6315US30D4+T reset circuit is a trustworthy component for safeguarding your digital systems.
