PMIC - Supervisors

The MAX6718AUKZWD2+T is a type of low-voltage supervisor device typically employed in battery-powered systems. It offers high accuracy reset triggering levels, low power consumption, and a wide range of supply voltages. This device is used to prevent latch-up caused by extreme voltage fluctuations and false reset and power-fail signals.

Applications

The MAX6718AUKZWD2+T is a supervisor specifically designed for battery-powered systems. It is often found in portable communication devices, automotive systems, and other embedded systems. It ensures system reliability by preventing false reset and power-fail signals in extreme voltage conditions. In addition, it helps protect from surges and brown-out conditions, as well as unwanted memory resets.

Working Principle

The MAX6718AUKZWD2+T uses a typical voltage monitoring circuit consisting of a voltage detector, a comparator, and a power switch. The voltage detector is set to detect the preset threshold voltage and the comparator compares it to an internal reference voltage to trigger the reset signal. When the input voltage falls below the preset threshold level, the comparator triggers the reset signal, which then switches off the power switch and thus shuts down the power supply to the system.

Features

The MAX6718AUKZWD2+T offers several features to ensure reliable protection from voltage fluctuations and false reset and power-fail signals. It has an adjustable reset threshold voltage, which can be adjusted for the specific application. It is available in a variety of packages, including DIP and SMT, for a wide range of applications. In addition, it has an active-low manual reset input and a power-on reset output.

Conclusion

The MAX6718AUKZWD2+T is a reliable low-voltage supervisor device for battery-powered systems. Its wide range of supply voltages, adjustable reset threshold voltage, and low power consumption make it ideal for portable communication devices, automotive systems, and embedded systems. Its features and working principle offer reliable protection from false reset and power-fail signals, ensuring system reliability.
