SC811ULTRT Application Field and Working Principle

Category: PMIC - Battery Chargers

The SC811ULTRT is a highly integrated, multi-channel, programmable digital battery management solution for electrical energy storage applications. It is an ideal choice for numerous battery pack applications, such as consumer electronics, digital automotives, medical products, and even industrial equipment. This single solution provides over-discharge protection, charge optimization, and power monitoring/management from one device.

Overview of Working Principle and Functions

The SC811ULTRT is equipped with a programmable main processor and 8 Automatic Battery Combined Controllers (ABCC). This combination is designed to protect the battery, optimize charge and discharge, and monitor and manage the power of the battery. The programmable main processor (MP) monitors multiple battery cells and the ABCCs ensure individual cell voltage protection. The ABCCs are also responsible for providing common mode regulation (CMR) during charge and discharge, as well as balancing through distributing excess charge or releasing excess voltage of a cell to maintain uniform cell voltage. The SC811ULTRT also provides two-wire serial peripheral interface (SPI, I2C, and S2C) communications for system monitoring and control.

Real-time monitoring

The SC811ULTRT provides real-time monitoring and management, enabling users to closely monitor the status of the battery pack at any stage of the charging process. This includes monitoring the voltage of each of the battery cells, temperature, current, time elapsed, total charge, total discharge, and more. The real-time monitoring also helps to increase system efficiency and safety by avoiding any overcharge, over-discharge, over-temperature, and over-current conditions.

Programmable Safety Settings

The SC811ULTRT also features programmable safety settings that can be adjusted to suit different applications. These safety settings enable users to specify the desired over-voltage, over-discharge, over-temperature, and over-current thresholds, ensuring that the battery is always operating safely and within desired parameters. In addition, the SC811ULTRT also features a delay start feature, helping to avoid peak current operations.

Charge/Discharge optimization features

The SC811ULTRT also includes several charge/discharge optimization features to improve system efficiency and extend the life of the battery. These features include Charge-Balde Discharge-Cutoff (C-B-D-C), Smart Discharge Cutoff (S-D-C), and Smart Charge Management (S-C-M). C-B-D-C enables the battery to be deeply discharged before being recharged, while S-D-C prevents the battery from being over-discharged. S-C-M helps to minimize the impact of over-charging on the battery by automatically subtracting charging time in order to maintain the charge level.

Conclusion

The SC811ULTRT is a highly integrated, multi-channel, programmable digital battery management device ideally suited for numerous battery pack applications. It provides real-time monitoring and management, enabling users to closely monitor the status of the battery pack at any stage of the charging process. Additionally, its programmable safety settings and charge/discharge optimization features help to increase system efficiency and extend the life of the battery.
