Product Overview: MAX6869UK19D1L+T by Maxim Integrated

The MAX6869UK19D1L+T is a versatile and reliable microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated, a renowned leader in the development of innovative analog and mixed-signal products. This compact, high-quality component is specifically engineered to monitor µP systems, providing essential functions such as power-on reset control, power-fail warning, and manual reset capability to ensure optimal system reliability and performance.

Encased in a small SOT-23 package, the MAX6869UK19D1L+T is ideal for space-constrained applications. It operates over a wide voltage range and features a factory-set reset threshold voltage of 1.9V, making it suitable for low-voltage operations. The device offers a reset timeout period of 1.6 seconds (minimum), ensuring that the µP has sufficient time to initialize properly during power-up or after a brownout condition.

The MAX6869UK19D1L+T is characterized by its low supply current, consuming only 7.5µA (typical), which significantly extends battery life in portable applications. This makes it an excellent choice for power-sensitive designs, such as handheld devices, IoT products, and other battery-operated electronics.

Additionally, this supervisory circuit integrates a debounced manual reset input, allowing external hardware, such as a push-button switch, to trigger a system reset. This feature provides an extra layer of control and safety, enabling users to manually reset the system whenever necessary.

Maxim Integrated's commitment to quality ensures that the MAX6869UK19D1L+T meets high standards of performance and reliability. It is designed to operate over the industrial temperature range of -40°C to +85°C, making it robust enough for use in harsh environments and demanding applications.

In summary, the MAX6869UK19D1L+T is a highly efficient, low-power µP supervisory circuit that offers essential monitoring functions required for stable and secure system operation. Its compact design, low power consumption, and robust feature set make it an excellent choice for designers looking to enhance the reliability of their microprocessor-based systems.
