The MAX6339JUT from Maxim Integrated is a precision, low-power, and highly integrated 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 used in portable consumer electronic devices, computers, controllers, and intelligent instruments.

Key Features

• Voltage Monitoring: The device offers precision monitoring of a single system supply voltage with a factory preset threshold, ensuring that the monitored voltage is maintained within the desired range for optimal system performance.
• Reset Output: The MAX6339JUT provides a reset output which remains asserted for a minimum timeout period after VCC has risen above the reset threshold level, ensuring a proper system reset during power-up, power-down, and brownout conditions.
• Low Power Consumption: Designed for battery-operated and low-power applications, this supervisory circuit has a low quiescent current that helps extend battery life.
• Compact Package: Available in a small SOT-23 package, the MAX6339JUT is suitable for space-constrained applications.
• Temperature Range: The device operates over an extended temperature range, making it versatile for various environments and applications.
