The MAX6347XR46+T from Maxim Integrated is a compact, highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of protection against low-battery conditions, power failures, and brownout conditions. This device is an essential component for systems that require a high degree of operational stability and uptime.

Key Features

• Precision Monitoring: The device features a precision factory-set V_CC reset threshold voltage of 4.63V, ensuring accurate monitoring and control over the power supply voltage.
• Low Power Consumption: Designed for energy-efficient operation, the MAX6347XR46+T has a low quiescent current of only 1.2µA, making it suitable for battery-operated applications.
• Manual Reset Input: It includes a manual reset input that allows for a system reset to be triggered with an external switch or logic signal, providing an additional layer of system control.
• Reset Output: The device offers an active-low reset output, which remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold. This ensures proper system reset and restart.
• Compact SOT-23 Packaging: The MAX6347XR46+T is available in a small, 3-pin SOT-23 package, making it ideal for space-constrained applications.
• Extended Temperature Range: The operating temperature range extends from -40°C to +125°C, accommodating a wide range of environmental conditions.
