The ADT7473ARQZ-1R7 is a thermal management processor designed for PMIC applications. The device combines both high-accuracy, stable, and reliable temperature sensing, along with high-speed Fan Speed Control (FSC) to support Fan On/Off and Stepwise. The ADT7473ARQZ-1R7 is specifically designed for wireless routers, personal computing, and gaming console applications.

The ADT7473ARQZ-1R7 incorporates a die temperature sensor and a three-terminal voltage-controlled fan driver that can be used by the system to control one or more fans. To control and monitor the fan, the ADT7473ARQZ-1R7 supports a selectable temperature range, setpoints, and their hysteresis values. It also provides settings to regulate the temperature based on the system needs.

The ADT7473ARQZ-1R7 is designed to actively cool the device requiring power management. The on-chip die temperature sensor provides temperature readings of the ADT7473ARQZ-1R7 that provides an accurate temperature reading of its own operations. The voltage-controlled fan driver allows the device to control fan speed, while the on-chip temperature comparators allow the setting of thresholds to activate the fan.

ADT7473ARQZ-1R7 also features on-chip over-temperature protection that detects when the die temperature exceeds a threshold and activates the fan. It also features a built-in watchdog timer to prevent the fan from staying turned on for too long and preventing damage to the system. The device supports a wide range of operating temperatures, making it suitable for applications in a variety of operating environments.

The ADT7473ARQZ-1R7 makes thermal management easier and more efficient. It is designed to ensure rapid fan speed control with minimal power consumption. The device can support two types of fan control, the stepwise mode and the on/off mode. In the stepwise mode, the device will increase the fan speed steadily until it reaches the desired level, while in the on/off mode it will switch the fan on and off at regular intervals to maintain an optimal temperature.

In addition to fan speed control, the ADT7473ARQZ-1R7 also features configurable temperature settings for emergency protection. If a certain temperature threshold is exceeded, the device will force the fan speed to its maximum speed and activate a system interrupt to send an alert. This level of protection can prevent damage to components or system failure due to high temperatures.

The ADT7473ARQZ-1R7 provides an efficient, reliable, and versatile solution for thermal management. With its integrated temperature sensors, voltage-controlled fan driver, and adjustable temperature settings, the ADT7473ARQZ-1R7 can simplify and streamline the implementation of thermal management in a system. In addition, its configurable settings and protection features make it an ideal choice for applications requiring accurate and reliable temperature monitoring.
