The MAX6467US44D3+T from Maxim Integrated is a compact, highly reliable, low-power voltage supervisory integrated circuit (IC) designed to monitor power supplies in microprocessor (µP) systems. This supervisory IC ensures that your system operates reliably by providing a reset signal to the µP during power-up, power-down, and brown-out conditions.

Key Features

• Supply Voltage Monitoring: The device can monitor a fixed supply voltage of 4.4V, ensuring that the system operates within the specified voltage range for optimal performance.
• Low Power Consumption: With its low supply current of 5.5µA at 3.3V, the MAX6467US44D3+T contributes to the overall energy efficiency of the system, making it an ideal solution for battery-powered applications.
• Reset Timeout: It features an internally fixed reset timeout period of 280ms (min), providing sufficient time for the µP to initialize and stabilize during power-up or after a brown-out reset.
• Operating Temperature Range: The device is designed to operate over a wide temperature range from -40°C to +125°C, ensuring reliable performance in a variety of environmental conditions.
• Form Factor: Offered in a small SOT-23 package, the MAX6467US44D3+T is suitable for space-constrained applications.
