PMIC - Battery Management: S-8200ACN-I6T1U Application Field and Working Principle

S-8200ACN-I6T1U is a 6-channel Li-ion/Li-polymer battery management device that is part of the PMIC - Battery Management family from ROHM. It is designed to provide precise battery cell protection and to facilitate the efficient management and monitoring of the battery pack. The device offers a wide range of features, including an adjustable over-current detection level, three-stage voltage level detection, an adjustable charge current, and an adjustable discharge current. Additionally, it features an internal temperature sensor and an adjustable temperature threshold that can be used to protect the battery pack from over-charging or over-discharging.

Applications

The S-8200ACN-I6T1U is designed to be used in battery-based systems that require advanced safety mechanisms for the protection of their components. The primary application field for this device is in consumer electronics, such as portable computers and cell phones. In addition, it can be used in medical devices and other battery-powered products. The device is also suitable for use in automotive applications such as electric vehicles, electric scooters, and plug-in hybrid electric vehicles.

Features and Functions

The S-8200ACN-I6T1U offers a wide range of features and functions, including the following:

• Adjustable Over-current Detection Level: An adjustable over-current detection level enables the device to detect and limit over-charge current and limit discharging currents, helping to protect the battery from over-charge or over-discharge.
• Three-stage Voltage Level Detection: This feature allows the device to detect the voltage of the battery pack in several stages, providing a greater sense of security and enabling the battery pack to be charged and discharged more safely.
• Adjustable Charge Current: The device can be configured to adjust the amount of current applied to the battery pack during charging, helping to optimize the battery charging process.
• Adjustable Discharge Current: This feature allows the device to regulate the amount of current flowing through the battery pack during discharging, helping to optimize the battery discharge process.
• Internal Temperature Sensor: This feature allows the device to monitor the temperature of the battery pack and to react accordingly by adjusting the current applied to the battery pack or shutting it down. This prevents the battery pack from overheating.
• Adjustable Temperature Threshold: The user can adjust the temperature threshold of the temperature sensor, allowing the battery pack to be protected in different ambient temperature ranges.

Working Principle

The working principle of the S-8200ACN-I6T1U is relatively straightforward. When the device is connected to the battery pack, it will monitor the voltage of the battery pack and, if the voltage exceeds the adjustable over-current detection level, the device will limit the current flowing through the battery pack in order to protect it from over-charging or over-discharging. The device also has an adjustable discharge current limit and a temperature sensor, which can be used to control the current flowing through the battery pack in order to optimize its charging and discharging process. In addition, the device can be configured to react to the temperature of the battery pack and to adjust the current applied to the battery pack accordingly.
