Maxim Integrated MAX6333UR18D3+T Voltage Supervisor

The MAX6333UR18D3+T is a high-quality voltage supervisor device designed and manufactured by Maxim Integrated, a company renowned for its innovative and reliable semiconductor products. This precision voltage supervisor is engineered to maintain system integrity by monitoring the power supply voltage of microprocessors (µPs) and digital systems, ensuring that the system operates at optimal levels and provides a reliable performance.

With a fixed-sense threshold voltage of 1.8V, the MAX6333UR18D3+T is ideal for applications that require a precise monitoring voltage level. It is particularly useful in systems where a stable and accurate voltage is critical for proper functionality, such as in portable devices, embedded systems, and other digital electronics that are sensitive to power supply variations.

This device offers a plethora of features that make it a standout choice for power management tasks. One of its key attributes is the ability to assert a reset signal whenever the VCC supply voltage falls below the preset threshold. The reset output remains asserted for a minimum reset timeout period after VCC rises above the reset threshold, ensuring that the system has adequate time to stabilize before resuming operation. This feature is crucial for preventing system malfunctions caused by brief power dips or brownouts.

The MAX6333UR18D3+T is packaged in a compact, surface-mount SOT-23, which is highly beneficial for space-constrained applications. Its small footprint allows for efficient use of board space without sacrificing performance. Moreover, the device is characterized for operation over a wide temperature range of -40°C to +85°C, making it suitable for use in environments that experience extreme temperature variations.

Additional features of this voltage supervisor include a low supply current, which is essential for battery-powered applications where power efficiency is paramount. The device also offers an active-low, push-pull reset output, which provides a quick and assertive response to voltage deviations, thereby enhancing the overall reliability of the system it is protecting.

In summary, the Maxim Integrated MAX6333UR18D3+T voltage supervisor is a high-precision, reliable, and efficient solution for maintaining the integrity of power supplies in digital systems. Its robust feature set, compact design, and wide operating temperature range make it an excellent choice for a variety of applications where voltage monitoring is critical.
