Product Overview: MAX6719AUTTWD1/V+T by Maxim Integrated

The MAX6719AUTTWD1/V+T is a highly reliable, quad supply microprocessor (µP) supervisory circuit, designed and manufactured by Maxim Integrated, a leader in the development of innovative analog and mixed-signal products. This component is engineered to monitor up to four system supply voltages, ensuring that electronic devices operate optimally within their power specifications. It is an ideal choice for multi-voltage systems looking for precise voltage monitoring and power management solutions.

With a small 6-pin SOT23 package, the MAX6719AUTTWD1/V+T is not only space-efficient but also features a low supply current of 8µA (typical), making it suitable for power-sensitive applications. The device offers factory-trimmed voltage thresholds for monitoring voltages of 1.8V, 2.5V, 3.3V, and 5V, which are common in digital systems. The accuracy of the voltage monitoring is ±1.5%, ensuring reliable operation of the system it is integrated into.

One of the key features of this supervisory circuit is its capability to assert a reset signal whenever any of the monitored voltages fall below their respective factory-set thresholds. The reset output is maintained for a minimum of 140ms after all voltages have risen above the reset thresholds, providing a predictable power-on reset for the µP. Additionally, the device includes a manual reset input that allows for a system reset to be triggered with an external signal.

The MAX6719AUTTWD1/V+T operates over a wide temperature range of -40°C to +125°C, making it suitable for use in harsh environments and industrial applications. It also supports a wide input voltage range, accommodating various power supply configurations.

In summary, Maxim Integrated's MAX6719AUTTWD1/V+T is a versatile and efficient solution for system voltage supervision. Its compact form factor, low power consumption, and high accuracy make it an excellent choice for designers who require reliable voltage monitoring to safeguard the integrity of their electronic systems.
