PMIC (Power Management Integrated Circuits) technologies have become a mainstay for electronics applications, providing efficient power delivery for components such as microprocessors, GPUs, RAM, and more. Supervisors are a key element of many PMIC designs and are used to monitor the performance and safety of the power delivery system, ensure proper operating voltage and current levels, and provide temperature monitoring and reporting.

The S-1009N28I-I4T1U is a supervisor IC designed by ROHM Semiconductor and provides features such as undervoltage protection, overvoltage protection, overcurrent protection, and temperature monitoring. This circuit provides fast and reliable protection for microprocessors and other components by using its integrated supervisor IC, which monitors and supplies the right amount of current and voltage depending on the environment conditions. This product is used for applications requiring high precision voltage monitoring, such as in Notebook PCs and digital home electronics.

The S-1009N28I-I4T1U from ROHM is a monolithic voltage supervisor IC with integrated MOSFET and overvoltage protection. It offers adjustable detection voltage with a wide input voltage range of 3.0V to 28V and 10 adjustable thresholds of 0.6V to 22.5V. The high-side NMOS device and the integrated logic circuit provide both low power consumption and overvoltage protection, making it suitable for a wide range of applications. In addition, the S-1009N28I-I4T1U features a wide operating temperature range of up to +125°C, so it can be used in harsh operating environments.

The S-1009N28I-I4T1U is designed with an integrated watchdog timer, enabling the circuit to reset the system or shut it down in the event of a fault. This feature is useful in monitoring the system\'s operation and ensuring that it is running correctly. The circuit also features a high-speed, low-current comparator, enabling it to detect and react quickly to changes in voltage. It also has a wide range of outputs, including reset/active low and active-high signals.

The working principle of S-1009N28I-I4T1U is based on the comparison of the actual voltage to a predefined threshold. When the applied voltage exceeds the threshold, the IC triggers an action, such as a reset signal. This reset signal is then interpreted by other components in the system, causing the system to reset itself or shut down. In addition, it also monitors and reports temperature, current, and voltage levels. This allows it to provide a detailed report on performance, allowing engineers and technicians to better diagnose power delivery system issues.

In summary, the S-1009N28I-I4T1U is a power management supervisor IC from ROHM Semiconductor that packs several features into one small package, such as overvoltage protection, undervoltage protection, overcurrent protection, watchdog timer, and temperature monitoring. It is ideal for applications that require precise voltage monitoring and can be used in a variety of environments, including harsh ones. Thanks to its integrated logic circuit and MOSFET, the S-1009N28I-I4T1U provides high precision voltage monitoring, efficient power delivery, and fast reaction to voltage variations.
