The MAX6773TATD2+T is a power management integrated circuit (PMIC) with integrated supervisor functions. An integrated chip is a device that incorporates multiple components in a single package, as opposed to a discrete chip, which uses separate components packaged in individual packages. Integrated circuits offer many advantages, including lower costs, higher performance, reduced power consumption, and higher reliability.

The MAX6773TATD2+T is designed to help protect electronic systems from possible damage caused by voltage and current overshoots, as well as by fault conditions. It is used in a wide range of applications, including automotive, computers, industrial, and medical systems.

Application Field

The MAX6773TATD2+T is a supervisor IC for monitoring power supplies and is used to provide a reliable and safe platform for system operations. It is used in automotive systems, such as battery management, power distribution, and power on reset. It can also be used in computers to protect against periodic overvoltage and in-rush current protection. It is also used in embedded applications to provide protection for processors and other embedded systems.

The MAX6773TATD2+T is also used in digital systems, such as digital set-top boxes, smart phones and tablets, to monitor the power and reset signals and prevent the system from crashing due to low voltage or overvoltage conditions. The device can also be used in industrial automation to ensure safe operation when connected to high-frequency switching systems. Additionally, it offers protection against reverse voltage in pump systems and other industrial applications.

Working Principle

The MAX6773TATD2+T is based on a standard power monitoring circuit, with additional features such as adjustable overvoltage and undervoltage thresholds, and watchdog timers. The device is designed to monitor the voltage, current, and temperature of the power supplies, and can detect and respond to overcurrent and overvoltage conditions. The device is also capable of generating signals that can be used as alarms or to de-energize the system.

The device also includes a watchdog timer that can be used to reset the system if it stops responding. The timer can be programmed to reset the system after a predetermined amount of time in case of a system freeze.

The MAX6773TATD2+T is also equipped with a pulse-by-pulse current limiter, which helps to protect the primary switch in the power supply by only allowing limited current to flow. This helps to prevent any overcurrent conditions. The device also has an adjustable overvoltage and undervoltage threshold that can be used to detect and respond to changes in the power supply voltage.

The MAX6773TATD2+T also offers extended temperature range and manufacturer-calibrated accuracy over the full operating temperature range. It can also be used in multiple-rail systems and is compatible with both manual and automated reset strategies.

In summary, the MAX6773TATD2+T is a PMIC with integrated supervisor functions, which is useful for a wide range of applications. It helps to protect electronic systems from damage caused by voltage and current overshoots, and is capable of generating signals that can be used as alarms or to de-energize the system in case of fault conditions. It also offers extended temperature range and manufacturer-calibrated accuracy over the full operating temperature range.
