Maxim Integrated MAX6713TEXS+T Microprocessor Supervisory Circuit

The MAX6713TEXS+T from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a single 3.3V power supply. This supervisory circuit is particularly suitable for portable and battery-powered applications due to its low power consumption and small footprint.

One of the key features of the MAX6713TEXS+T is its ability to assert a reset signal whenever the VCC supply voltage falls below a preset threshold, ensuring that the µP starts up in a known state. The reset output remains asserted for a period after VCC has risen above the reset threshold, providing the system with a stable interval to initialize. The reset threshold voltage for this device is precision-trimmed to 2.93V, which is ideal for 3.3V-powered systems.

The device comes in a compact 4-pin SC70 package, which is highly space-efficient for modern electronics where board space is at a premium. It operates over a wide temperature range, from -40°C to +85°C, making it versatile for various industrial applications. The MAX6713TEXS+T also features a low supply current of 5.5µA (typical), which is beneficial for power-sensitive designs.

Additional features of the MAX6713TEXS+T include a manual reset input, which allows the system to be reset from an external switch or a supervisory processor. This input is debounced to ensure reliable operation. The device also offers an active-low open-drain reset output, providing compatibility with a variety of digital systems.

Overall, the Maxim Integrated MAX6713TEXS+T is an essential component for system reliability, providing crucial monitoring and control for applications that cannot afford to have system failures due to power issues. Its ease of integration, combined with Maxim's reputation for quality, makes it a top choice for designers looking to enhance system stability and robustness.
