PMIC (power management ICs) are digital circuits that are used to provide power management and monitoring in a device. Thermal management is an important part of power management, and PMICs can be used to regulate and monitor temperature in a device. The ADT7475ARQZ-REEL is an example of a PMIC that is designed specifically for thermal management. This device provides an integrated temperature sensor, temperature monitor, and thermal protection circuit in a single package.

The ADT7475ARQZ-REEL is a 16-pin dual-supply device that monitors hot-spot and cold-spot temperatures simultaneously. It can detect hot and cold temperature states with a resolution of 1°C, and provides an output indicative of the temperature state. The device operates between -40°C to +125°C, and the hot-spot and cold-spot temperature (TH and TC) are monitored by comparing them to user configurable set-point thresholds, which can be adjusted on the fly.

The ADT7475ARQZ-REEL also includes a built-in thermal protection circuit. This circuit provides hysteresis thresholds that will be triggered when the hot-spot temperature goes above or the cold-spot temperature goes below a certain limit. Upon triggering, the circuit will pull the TH / TC set-point threshold to a safe reset value, which reduces the device power dissipation and eliminates the thermal hazard condition.

The ADT7475ARQZ-REEL is designed for a wide range of applications, including in embedded systems, appliances, HVAC systems, and automotive components. In addition to providing temperature sensing and monitoring, the device also reduces power consumption. This makes it particularly suitable for mobile applications, where battery life and power consumption are important considerations.

In conclusion, the ADT7475ARQZ-REEL is a specialized PMIC designed specifically for thermal management. It offers integrated temperature sensing, temperature monitoring, and thermal protection, allowing the device to detect and protect against thermal hazards in a wide range of applications. In addition, it also reduces power consumption, making it suitable for mobile applications.
