S-8205BAI-TCT1U

PMIC - Battery Management

The S-8205BAI-TCT1U is a power management integrated circuit (PMIC) designed to provide advanced battery management functions required in modern day smart devices which are powered by a single cell Li-ion or Li-polymer battery. This product is composed of an 8bit 8051 core microcontroller, battery charger controller, LCD driver and several analog switches. It has a wide range of features, including over-current protection, over and under voltage protection, temperature monitoring, hardware based remote shutdown and power on and off control.

Application

S-8205BAI-TCT1U is often used in mobile handsets and portable consumer electronics such as phones, tablets, digital cameras, and portable media players. In addition, the high integration level of the device and minimal external components makes it attractive for incorporation into other types of electronics, such as wearable devices and medical monitoring products.

Working PrincipleThe device supports a wide range of battery chemistries including Li-ion and Li-polymer, and supports both charge through USB and AC/DC adapter. It features low-battery voltage protection, high-battery voltage protection, over current protection, and over temperature protection. Its various features make it suitable for a wide range of applications.

The charging and discharging of the battery is controlled by an analog switch, which is controlled by the 8 bit 8051 core microcontroller. This controller monitors the battery voltage and current, and switches off charging and discharging when it is not necessary. It also monitors the battery temperature and will switch off the battery charging and discharging if the temperature exceeds a certain threshold.

The device also features a LCD driver, which allows the user to monitor the battery status in real-time. It specialises in displaying battery-related information such as voltage, current, temperature and charge level. This is especially useful in applications where the battery is being used intensively, such as in mobile phones.

The device also features a hardware-controlled power on and off function, which means it can be triggered remotely. This is particularly useful in the case of mobile phones and other consumer electronics which are allow to be shut down remotely by the user, or by an outside source such as the network provider.

Conclusion

The S-8205BAI-TCT1U is a highly integrated PMIC designed for use in battery-powered consumer electronic devices. It features a wide range of safety and monitoring functions, including over-current protection, over and under voltage protection, temperature monitoring, and hardware-controlled remote power on and off. Its advanced features make it attractive for incorporation into a wide range of battery-powered devices, such as mobile phones and other consumer electronics.
