The MAX6378XR44+T is a precision, low-power, low-voltage microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a 4.4V power supply voltage.

Key Features

• Voltage Monitoring: This device offers precision monitoring of a 4.4V power supply with a factory-set reset threshold, ensuring that the system operates within safe voltage levels.
• Reset Output: The MAX6378XR44+T provides a reset output which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold. This ensures a proper system reset during power-up, power-down, or brown-out conditions.
• Low Power Consumption: Designed for energy-efficient applications, the device operates with a low quiescent current of only 1.2µA, making it ideal for portable and battery-operated equipment.
• High Accuracy: With a ±2.5% reset threshold accuracy over the entire temperature range, it ensures reliable monitoring and system protection.
• Compact Package: The MAX6378XR44+T comes in a small, 3-pin SC70 package, which is highly suitable for space-constrained applications.
