Product Overview: MAX6366LKA31+ from Maxim Integrated

The MAX6366LKA31+ is a highly reliable, low-power microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated. This compact device is engineered to monitor power supplies in µP and digital systems, providing a crucial safeguard against power failures or low voltage conditions. It is an ideal solution for maintaining system integrity and preventing data corruption during adverse power conditions.

The MAX6366LKA31+ operates by monitoring the supply voltage and asserting a reset signal to the µP whenever the supply voltage drops below a preset threshold. This reset signal remains asserted until the supply voltage returns to an acceptable level and a preset timeout period has elapsed, ensuring that the µP restarts in a known state. The reset threshold for the MAX6366LKA31+ is factory-set at 3.08V, which is suitable for a wide range of applications.

Notably, this supervisory circuit features a low supply current of only 1.5µA at +25°C, making it an energy-efficient choice for battery-powered and portable devices. Its wide operating voltage range from 1.2V to 5.5V provides versatility for different system requirements. The MAX6366LKA31+ comes in a compact SOT-23 package, which is highly beneficial for space-constrained applications.

Additional features of the MAX6366LKA31+ include a manual reset input, which allows for an external trigger to initiate a system reset. This can be particularly useful during system maintenance or troubleshooting. The device also offers a debounced manual reset input, which ensures that the reset signal is clean and free of glitches that could cause unintended system behavior.

In summary, the MAX6366LKA31+ is a robust and reliable supervisory circuit that provides essential protection for digital systems. With its low power consumption, precise voltage monitoring, and compact design, it is a practical choice for a range of applications including portable devices, embedded systems, and other electronics requiring a stable and reliable operation.
