PMICs, or power management integrated circuits, are controllers and integrated circuits used to manage and monitor power supply in an electrical system. They are critical parts of any system that must maintain consistent regulated voltage or current. One common subcategory of PMICs is supervisors, which are integrated circuits designed to monitor power supply levels to ensure safety, performance, and reliability. The MAX6751KA16+T is one such supervisor, used in a wide range of applications, from consumer electronics to industrial control and medical devices. In this article, we will discuss the application field and working principle of the MAX6751KA16+T.

Applications of the MAX6751KA16+T range from consumer electronic products such as digital televisions, set-top boxes, and portable electronic devices (including smartphones, digital cameras, and tablets) to a wide range of industrial control applications such as circuit breakers, contactors, and remote control systems. It can also be used in medical equipment such as anesthesia, ventilators, and patient monitors. This makes the MAX6751KA16+T an extremely versatile and ubiquitously used PMIC.

The working principle of the MAX6751KA16+T is based around its two main functional units: a differential linear voltage monitor and a temperature-compensated reset circuit. The voltage monitor maintains two reference voltages, one higher than the operational voltage and one lower, and thus the voltage monitor’s output is active when the monitored voltage is between these two voltages. The temperature-compensated reset circuit contains a pair of comparators that generate a reset signal when the reset voltage drops below their respective trip points. This reset signal initiates a reset that begins the process of restoring power. The reset circuit will then monitor the reset voltage and delay the reset output until it is above both trip points. Additionally, the MAX6751KA16+T includes an overvoltage protection (OVP) circuit, which disables the device if the monitored voltage is higher than a predetermined OVP trip point.

The MAX6751KA16+T is a highly reliable monitoring and protection device optimized for consumer, industrial and medical applications. The voltage monitor ensures that the regulator output remains within a programmable range, while the temperature-compensated reset circuit and OVP ensure the protected system is restarted and fully operational when an overvoltage or undervoltage condition is detected. Overall, the MAX6751KA16+T is an outstanding choice for monitoring and prototyping applications that demand high accuracy and reliable operation.
