Power Management Integrated Circuits (PMICs) are used in a wide range of electronic products to provide efficient and reliable control of their power input and output. Supervisors, a type of PMIC, are used to protect equipment from unstable or undesirable electrical conditions by monitoring their voltage and current levels. One such supervisor is the MAX6379UR44+T, which is designed to be an integrated two-channel supervisor for monitoring, voltage, and current levels in a variety of applications. This article will explore the application field of the MAX6379UR44+T, as well as its working principle and features.

Application Field

The MAX6379UR44+T is designed to be used as a two-channel supervisor for monitoring, voltage, and current levels in a variety of applications. It offers a wide input voltage range of 2.5V to 33V, and can monitor voltages up to 95V. It is suitable for use in equipment such as notebook and tablet PCs, medical devices, automotive battery management systems, industrial controllers, and PC hardware and peripherals. In these applications, the MAX6379UR44+T can be used as a watchdog, over-voltage/over-current protection, an undervoltage lockout, or a multiple output power supervisor.

Working Principle

The MAX6379UR44+T is designed to provide two independent monitoring circuits, allowing it to protect two independent boards or systems from electrical hazards. Each monitoring circuit has three voltage inputs: the main voltage input, a comparator voltage input, and an overvoltage/overcurrent input. The outputs are latched on overvoltage/overcurrent detection and can be reset either externally or automatically. The MAX6379UR44+T supports watchdog timers up to 655 msec and can be set to a window watchdog mode to ensure that the voltage and current levels are above a user-defined minimum and maximum values. This supervisor also has a programmable reset timer for delayed system reset.

Features

The MAX6379UR44+T offers a number of features that make it suitable for a wide range of applications. It is small and low-power, making it ideal for space-limited or energy-restricted applications. The device is highly reliable, with a precision voltage detector that ensures the system is always supplied with accurate voltage information. It has an on-board temperature-sensing function that can detect operating temperature, and a built-in undervoltage lockout function that prevents the system from power-cycling due to low voltage levels. Finally, it is equipped with a current-limit vector detection system, which helps protect systems from over-current and reverse-current problems.

In conclusion, the MAX6379UR44+T is a highly reliable, low-power, two-channel supervisor that is suitable for use in a wide range of applications where protection from unstable or undesirable electrical conditions is required. This supervisor includes a wide-input voltage range, a precision voltage detector, a temperature-sensing function, and an undervoltage lockout. With these features, the MAX6379UR44+T is a versatile and reliable tool for monitoring and protecting equipment from electrical hazards.
