The S-8225BAC-TCT1U is a battery charging management IC (PMIC) designed for use in Li-ion and Li-polymer battery powered applications. The device features a Charge Control System which provides over-current protection, thermal control, and a status monitoring system for the battery packs. The device is designed for the battery packs with two or three series Li-ion/Li-polymer cells. It consists of an integrated DC/DC converter and two linear charge controllers.

The DC/DC converter of the S-8225BAC-TCT1U supports an efficient and safe charge of a 2- to 3-cell Li-ion/Li-polymer battery pack. The input voltage range is between 3V to 14V, and the output voltage can be set up to 8V. The device allows independent setting of battery charge current, charge voltage, and charge termination current. It also supports fast-charge and trickle-charge.

The S-8225BAC-TCT1U has two linear charge controllers with over-current protection and thermal control capability. The first linear charge controller is used to charge the battery pack, while the second controller is used to monitor the charge status of the battery pack. The first linear charge controller features a built-in control loop for fast charging current regulation. The second controller features an adjustable termination current setting and a timer, allowing for safe and reliable charging of the battery pack.

The battery charging management IC (PMIC) also includes a battery voltage monitor and a power-down circuit. The voltage monitor monitors the voltage of each cell in the pack, and activates the power-down circuit when the battery is fully charged. Finally, the device supports various batteries such as Li-ion and Li-polymer cells.

The S-8225BAC-TCT1U is suitable for many consumer applications as well as portable medical systems, test equipment, and remote sensing systems. It is ideal for applications which require high safety and low cost, as well as reliable, efficient and accurate charge management.

In conclusion, the S-8225BAC-TCT1U PMIC is a versatile and cost-effective charge control solution for Li-ion and Li-polymer battery packs. It features an integrated DC/DC converter and two linear charge controllers for safe and accurate charge management, as well as a battery voltage monitor and a power-down circuit. The device is suitable for various consumer and medical applications and is ideal for applications which require high safety, low cost, and reliable, efficient and accurate charge management.
