Maxim Integrated MAX6377UR26+T Voltage Detector

The MAX6377UR26+T is a precision microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides a significant level of system reliability and accuracy required in critical electronic applications. This device is specifically engineered to keep systems within their operational voltage thresholds, ensuring proper function and stability.

Featuring a factory-set reset threshold voltage of 2.63V, the MAX6377UR26+T is capable of holding a µP in reset until the system voltage has stabilized at the valid level for reliable system operation. This reset signal is maintained for a minimum of 140ms after the supply voltage surpasses the reset threshold, providing ample time for the system to stabilize upon power-up.

One of the key benefits of the MAX6377UR26+T is its low power consumption, drawing only 1.6µA of supply current. This makes it an ideal choice for portable and battery-operated equipment where power efficiency is crucial. The device operates over a wide voltage range from 1.2V to 5.5V, which provides flexibility for use in various applications.

The compact SOT-23 packaging of the MAX6377UR26+T allows for a minimal footprint on the PCB, saving valuable board space in space-constrained applications. Its robust design ensures reliable operation over a broad temperature range of -40°C to +125°C, making it suitable for use in harsh environments.

With its built-in hysteresis, the MAX6377UR26+T prevents erratic system reset operation when the input voltage is near the reset threshold, thus providing a stable reset signal without false triggering. This feature is particularly important in noisy environments where power supply fluctuations are common.

In summary, the Maxim Integrated MAX6377UR26+T voltage detector is a high-quality, reliable component that offers precise voltage monitoring, ultra-low power consumption, and a small form factor, making it an excellent choice for a wide range of applications including portable devices, embedded systems, and industrial equipment where consistent and accurate voltage supervision is critical.
