Maxim Integrated MAX6839XSD3+T Voltage Supervisor IC

The Maxim Integrated MAX6839XSD3+T is a highly reliable, low-power voltage supervisor designed to monitor single-system voltages. This component is part of Maxim's family of microprocessor (µP) supervisory circuits that are engineered to maintain system integrity by monitoring the power supply and system voltage levels. The MAX6839XSD3+T is an ideal solution for a wide range of applications, including portable devices, computers, controllers, and intelligent instruments.

This voltage supervisor IC is characterized by its small form factor, being available in a compact, 4-pin SC70 package, which is suitable for space-constrained applications. It operates over a wide voltage range and is preset with a factory-trimmed threshold voltage of 3.08V, making it well-suited for 3.3V-powered systems that require precise voltage monitoring to ensure proper operation.

One of the key features of the MAX6839XSD3+T is its low power consumption, which helps to extend the battery life in portable applications. The IC consumes a typical quiescent current of only 1.5µA, which is beneficial for power-sensitive designs. Additionally, it offers a ±1.5% threshold accuracy over the entire operating temperature range of -40°C to +125°C, ensuring reliable performance under varying environmental conditions.

The device includes a manual reset input, allowing the system to be reset manually if necessary. The reset output is available in both push-pull and open-drain configurations, providing flexibility for interfacing with different types of microprocessors or digital systems. The reset signal is guaranteed to remain valid with VCC as low as 1.0V, ensuring the system can be reliably reset even under low-voltage conditions.

For applications requiring a watchdog timer or additional voltage monitoring inputs, Maxim Integrated offers other devices in the same family with those features. The MAX6839XSD3+T, with its robust set of features, stands out as a high-quality component for systems that demand accurate voltage supervision to maintain proper functionality and safety.

In summary, the MAX6839XSD3+T from Maxim Integrated is a versatile and energy-efficient solution for voltage supervision in a variety of electronic systems. Its precision, small size, and low power consumption make it an excellent choice for designers looking to enhance system reliability without compromising on space or power efficiency.
