The S-8225AAB-TCT1U is a single-cell Li-ion battery monitoring application circuit (PMIC - Battery Management) developed by Rohm Semiconductor. This PMIC is specifically designed for consumer and industrial applications that use a single-cell Li-ion battery. It includes two dedicated analog inputs for voltage and current measurements, as well as digital inputs and outputs with an SPI and I2C interface that allow the user to monitor and control the system. The S-8225AAB-TCT1U supports a wide range of voltage and current settings, providing adjustable thresholds that allow the user to monitor and control the battery.

The S-8225AAB-TCT1U is designed to maximize power efficiency and accuracy in a single device, saving cost and space in the overall system design. Its high-speed analog environment enables accurate, real-time measurement of battery voltage and current, while the integrated op amp and MOSFET switch provide a robust solution that can drive higher currents and reduce power consumption.

The S-8225AAB-TCT1U has advanced protection features, such as over-current protection, to ensure safety and reliability in applications. It also has an adjustable over-voltage protection function that prevents excessive battery charging and discharging. This protection is further augmented by an integrated open-drain output that can be used to alert the system in the event of over- charging or under-charging.

The S-8225AAB-TCT1U is designed to be extremely easy to use, with intuitive commands and settings that can be quickly adjusted via the I2C and SPI interface. The built-in developer’s configuration tool provides a range of settings that can be quickly tailored to any specific application. This tool simplifies the development process by eliminating the need to manually enter data and settings into the chip.

The S-8225AAB-TCT1U helps in extending the life of the battery in applications by monitoring battery voltage and current as well as providing protection features. In addition, the built-in developer’s configuration tool makes it easier for system designers to quickly and accurately tailor their settings for specific applications. This PMIC is ideal for consumer and industrial single-cell Li-ion battery applications, from charging, to car ignition systems, to long distance tracking devices.
