Maxim Integrated MAX6414UK23+T Microprocessor Reset Circuit

The MAX6414UK23+T is a sophisticated microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a 2.3V power supply voltage. This device is particularly well-suited for portable and battery-powered equipment due to its low power consumption and compact SOT-23 packaging.

Key Features

• Reset Output: The MAX6414UK23+T offers an active-low reset output, which ensures that the connected µP and other components in the system are held in the reset state until the system voltage has stabilized.
• Reset Timeout: It features a preset reset timeout delay of 140ms (min), which provides a reliable reset signal and ensures proper system restart and initialization.
• Low Power Consumption: With its ultra-low supply current of 1.5µA (typ), this device is energy-efficient, making it ideal for power-sensitive applications.
• Voltage Monitoring: The device precisely monitors the 2.3V power supply, providing high accuracy in power-fail detection and reset assertion.
• Temperature Range: The MAX6414UK23+T is designed to operate over a wide temperature range, from -40°C to +125°C, ensuring reliability across various environmental conditions.
• Compact Packaging: It comes in a small 5-pin SOT-23 package, which minimizes the footprint on the PCB and is suitable for space-constrained applications.
