The S-8211AAK-I6T1G is a battery management product from ROHM Semiconductor. The S-8211AAK-I6T1G is a highly efficient and reliable single-channel system for linear current monitoring and power supply protection. This device is well-suited to be used in the protection of battery packs from over-current, over-voltage and over-temperature conditions.

The application field of the S-8211AAK-I6T1G is mainly in lithium-ion battery packs. It is used in a wide range of applications, such as Smartphones, PDAs, tablets, gaming consoles, digital cameras, wearable devices, and other battery operated devices.

The S-8211AAK-I6T1G has built-in over-voltage protection and over-temperature detection circuits, which make it ideal for protecting the battery during use. The over-voltage protection is adjustable from 2.5V to 4.7V to provide some flexibility according to the specific application. The over-temperature detector works by monitoring the die temperature and cutting off the power supply when the temperature exceeds a pre-set value.

The S-8211AAK-I6T1G is also capable of linear current monitoring. This function detects changes in the battery\'s current, allowing the system to better evaluate the health of the battery, and provide more accurate charge and discharge data. The device also has adjustable current limit, under voltage lockout and programmable output voltage levels.

In terms of working principle, the S-8211AAK-I6T1G uses a single wire to monitor the current in the battery pack. When the current exceeds the maximum allowed value, the device shuts down the battery pack and trips the over-current protection circuit. The over-voltage protection circuit is triggered when the voltage reaches the over-voltage level, while the over-temperature protection circuit is triggered when the die temperature exceeds the maximum allowed value. The S-8211AAK-I6T1G also monitors the linear current, and has adjustable over-current, over-voltage and over-temperature thresholds.

The S-8211AAK-I6T1G is a reliable, efficient and cost-effective battery management system. It can be used in a wide range of applications, from wearables and gaming consoles to digital cameras and smartphones. Its built-in linear current monitoring and protection circuits provide additional safety and reliability to battery packs, making it the ideal PMIC - Battery Management solution.
