Maxim Integrated MAX6361LUT23 Microprocessor (µP) Supervisory Circuits

The MAX6361LUT23 from Maxim Integrated is a highly reliable microprocessor supervisory circuit designed to maintain system integrity during power failures or unexpected events. This compact and efficient device is a quintessential component for managing the correct operation of µP systems by monitoring the power supply voltage levels and ensuring that the µP and its peripherals are reset properly during power-up, power-down, or brown-out conditions.

Encased in a small 6-pin SOT23 package, the MAX6361LUT23 offers a low supply current feature, making it an ideal choice for portable and battery-powered applications where power efficiency is critical. With its precision factory-set voltage thresholds, the device ensures that systems are protected against unpredictable voltage fluctuations, which can lead to data corruption or system failures.

One of the key features of the MAX6361LUT23 is its ability to provide a reset signal to the µP for a minimum of 140ms after VCC has risen above the reset threshold level. This ensures that the µP and its peripherals are held in a reset state until the power supply has stabilized, thus allowing for a safe system start-up. Moreover, the MAX6361LUT23 offers an active-low RESET output, which remains asserted while VCC is below the reset threshold, and for a period after VCC rises above the reset threshold.

The device operates over a wide voltage range and is characterized for operation from -40°C to +85°C, making it suitable for use in a broad range of environments and applications. Its low component count and ease of use also contribute to a simplified design process, reducing time to market for products that incorporate this supervisory circuit.

In summary, the Maxim Integrated MAX6361LUT23 is a robust and essential component for any system requiring reliable voltage monitoring and reset capabilities. Its compact size, precision voltage monitoring, and low power consumption make it a top choice for designers looking to enhance system reliability and performance.
