Introduction to the S-8200ADE-I6T1U

The S-8200ADE-I6T1U is a device from STMicroelectronics from its STM32H7 high reliability and low-power family of microcontrollers with integrated Power Management Intelligent Circuits (PMICs). Together, these devices provide a comprehensive platform for battery management applications. This article provides an overview of this device\'s features and applications in battery management.

Application Fields and Working Principles
The S-8200ADE-I6T1U is suitable for applications requiring a high level of reliability and low power consumption. Specifically, it is ideal for applications in consumer and industrial automation, automotive, battery powered devices and lighting.

The S-8200ADE-I6T1U includes a dual output synchronous switch-mode power supply controller, an LDO regulator and a battery management peripheral, integrated in an 8/16-bit MCU-based 8x8 mm QFN package. The MCU is of STM32H7 series and is clocked with a frequency of 8 MHz.

The device implements buck or boost topologies with two separate outputs for the positive and the negative rails; the two outputs may be set to different voltages. The device features a built-in LDO for providing supply or standby power for the applications. The LDO supports input voltage range of 2.4~5.5V and output voltage range of 0.8~3.3V.

The battery management peripheral has all the features like Battery Monitoring, Trickle Charge, Termination, and over-voltage/current/temperature protection on both charge and discharge side. The inputs are programmable and are scalable up to 22-V. The device includes the ability to detect battery types and lithium-ion cell size.

The device is capable of automatically detecting battery types and high cell count batteries. Moreover, it has a built-in linear charger with automatic selection of the charging current, according to the battery type and size. This allows the device to charge single-cell Li-Ion, Li-Polymer and LiFePO4 batteries at up to 4.1V.

In addition, the device has built-in protection for the two rails with adjustable over-voltage, over-current, and over-temperature thresholds, as well as adjustable charge termination thresholds. It also supports programmable power on/off sequencing and low-load shutdown.

Conclusion

The S-8200ADE-I6T1U is a low-power and highly integrated PMIC suitable for battery management applications such as consumer and industrial automation, automotive, battery powered devices and lighting. The device includes a dual synchronous switch-mode power supply controller and an LDO regulator integrated with a battery management peripheral. It supports programmable power on/off sequencing, adjustable charge termination thresholds, detection of battery types and size and protection on both the charge and discharge sides.
