Maxim Integrated MAX6365LKA23-T Supervisory Circuit

The MAX6365LKA23-T from Maxim Integrated is a precision microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides a significant level of system reliability and accuracy required in critical applications. This supervisory circuit ensures that the µP boots up in a predictable state every time the power is applied and helps in managing power failure or brownout conditions effectively.

Featuring a combination of low supply current, small footprint, and precision voltage monitoring, the MAX6365LKA23-T is an ideal choice for portable and space-constrained applications. The device operates over a wide voltage range and has a factory-trimmed reset threshold suitable for monitoring 3.3V-powered systems.

Key features of the MAX6365LKA23-T include:

• Reset Output: The device provides a reset output during power-up, power-down, and brownout conditions. The reset output remains asserted for a preset timeout period after VCC has risen above the reset threshold, ensuring the system has stabilized before the µP starts operation.
• Low Power Consumption: With its low supply current of only 1.2µA, this supervisory circuit is energy-efficient, making it suitable for battery-operated devices.
• Manual Reset Input: A manual reset input allows for a system reset to be triggered with an external pushbutton or logic signal, providing an additional layer of system control.
• Watchdog Timer: The integrated watchdog timer ensures that the µP does not hang in an unresponsive state, thereby improving system reliability.
• Compact SOT-23 Packaging: The device is available in a small, 8-pin SOT-23 package, making it easy to integrate into design layouts where space is at a premium.

Applications for the MAX6365LKA23-T include portable devices, computers, controllers, and intelligent instruments where precise monitoring of the power supply voltage is critical for proper operation. Its robust feature set ensures that systems remain operational and reliable under varying power conditions, making it a trusted component for designers and engineers looking to enhance their system designs.

Maxim Integrated's commitment to quality and innovation is evident in the MAX6365LKA23-T supervisory circuit, providing a cost-effective solution for power management in sophisticated electronic systems.
