Maxim Integrated MAX6719UTYHD3+ Supervisory Circuit

The MAX6719UTYHD3+ is a highly reliable supervisory circuit designed by Maxim Integrated, a leader in analog and mixed-signal engineering. This compact device is engineered to monitor power supplies in microprocessor (µP) and digital systems, ensuring that the system operates correctly during power-up, operation, and power-down. Its primary function is to provide a precise, low-power voltage monitoring solution for complex electronic systems.

Featuring a quad voltage monitor, the MAX6719UTYHD3+ is capable of supervising up to four system voltages simultaneously, making it an ideal choice for multi-voltage systems. It boasts a low supply current of only 7µA, which is highly beneficial for battery-powered applications where power efficiency is crucial. The device operates over a wide voltage range, typically from 1.8V to 5.5V, providing versatility for various applications.

One of the key features of the MAX6719UTYHD3+ is its adjustable voltage threshold options. This allows designers to set precise voltage thresholds according to their specific system requirements. The supervisory circuit also includes a manual reset input, enabling a system reset to be triggered with an external push-button or logic signal.

The device is equipped with an active-low reset output, which remains asserted for a minimum of 140ms after all the monitored voltages have risen above the programmed thresholds. This ensures a proper system reset and startup. The reset logic is designed to be immune to short duration voltage transients, providing additional system stability.

Housed in a compact SOT-23 package, the MAX6719UTYHD3+ is designed for space-constrained applications. Its small footprint makes it an excellent choice for portable devices, industrial controllers, and automotive systems where space and power efficiency are at a premium.

Maxim Integrated's commitment to quality and reliability is evident in the MAX6719UTYHD3+, with its built-in features that safeguard system integrity under various conditions. This supervisory circuit is a robust solution for maintaining the health and stability of your electronic systems.
