Maxim Integrated MAX6315US45D3+: Precision Voltage Monitoring

The Maxim Integrated MAX6315US45D3+ is a high-quality, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring nominal system voltages of 4.5V.

This device is specifically engineered to maintain system integrity by monitoring the power supply voltage. In the event of an undervoltage (UV) condition, the MAX6315US45D3+ asserts a reset signal to prevent system errors. The reset output remains asserted until the voltage returns to an acceptable level and a reset timeout period has elapsed, ensuring the system has stabilized before continuing operation.

Key Features:

• Precision Voltage Monitoring: The MAX6315US45D3+ offers a factory-set reset threshold voltage, tailored for 4.5V systems, which eliminates the need for external resistors and adjustments.
• Low Power Consumption: With its low power consumption design, this supervisory circuit is an ideal choice for portable and battery-powered applications.
• Reset Timeout: It features a fixed reset timeout period that ensures the system has sufficient time to recover before resuming operation.
• Manual Reset Input: A manual reset input is provided, giving users the ability to trigger a system reset whenever necessary.
• Compact SOT-143 Package: The compact package size is beneficial for space-constrained applications, without compromising on performance and reliability.

Applications:

The MAX6315US45D3+ is versatile and can be used in a wide range of applications, including:

• Portable/Battery-Powered Equipment
• Computers and Controllers
• Embedded Systems
• Data Storage Equipment
• Telecommunications Systems

With its precision monitoring capabilities and robust feature set, the Maxim Integrated MAX6315US45D3+ is an essential component for ensuring the stability and reliability of digital systems operating at 4.5V power supply levels.
