A PMIC (Power Management IC) is a central control device in electronic system design, providing a range of voltage regulation, power management and thermal control features. Thermal management ICs are one of the most important types, as thermal control and prevention of overheating are essential for the safe and reliable operation of electronic systems. The ADT7476AARQZ-R offers a comprehensive solution for thermal management, featuring an integrated temperature sensor, programmable thermal triggering levels, output protection and thermal limits. In this article, we take an in-depth look at the features, applications and working principle of the ADT7476AARQZ-R.
ADT7476AARQZ-R Overview: The ADT7476AARQZ-R is a high-performance, power management, thermal management IC designed to provide system-level thermal protection. The device combines an integrated temperature sensor, adjustable thermal trip point, thermal limit and protection circuitry, along with configurable current limit, voltage limit, analog-to-digital converter and I/Os. The ic supports both low voltage and high voltage versions, with the low voltage version covering supply voltages from 2.6V to 5.5V, while the high voltage version covers 4.0V to 20.0V. Other features of the ADT7476AARQZ-R include two programmable drive voltages, internal clock, an integrated temperature sensor, programmable thermal triggering levels, output protection and thermal limits. The device is offered in a 20-pin QSOP package.
Applications: The ADT7476AARQZ-R can be used in a variety of applications, including motor control, AC and DC motor drives, desktop PCs, servers, mobile phones and tablet computers. The device is well suited for thermal protection of embedded systems, providing real-time thermal management by monitoring the junction temperature and responding with appropriate actions. In addition, the ADT7476AARQZ-R can be used to provide output over-voltage, over-current and thermal protection, with programmable current and voltage limit thresholds and an adjustable thermal trip point. The integrated temperature sensor and programmable thermal trip points also make the device an ideal choice for monitoring and protection of high-power heat sinks.
Working Principle: The ADT7476AARQZ-R works by controlling the power output to the load through the use of current and voltage limit thresholds and programmable thermal trip points. The integrated temperature sensor monitors the junction temperature of the device and adjusts the current and voltage limits accordingly. If the temperature exceeds a pre-defined threshold, the device will automatically shut down the output, protecting the system from potential damage caused by overheating. In addition, the device can be configured to support a range of fault responses, including restarting the system, shutting down power, cycling the power, etc.
The ADT7476AARQZ-R is an ideal choice for thermal protection of embedded systems, providing system-level thermal protection. Its integrated temperature sensor, programmable current and voltage limits, adjustable thermal trip point and output protection features make it an ideal choice for a wide variety of applications where thermal management is required. The device can be used in motor control, AC and DC motor drives, desktop PCs, servers, mobile phones and tablet computers, providing reliable and efficient thermal protection for high-power applications.
