The S-8244AAMFN-CEMT2G, classified as a PMIC (Power Management Integrated Circuit) – Battery Management product, is an integrated power supply integrated circuit specifically designed to control and monitor multiple power rails and manage various battery functions in an electronic system. This PMIC is based on micro-electronics design and provides a circuit solution for extending the current and voltage measurement range for battery management and other applications.

S-8244AAMFN-CEMT2G provides supply voltage from 1V to 20V and current from 1mA to 2A; it’s able to monitor three different power rails and enter sleep mode when current is low to save power consumption. The built-in Over-Voltage Protection (OVP) and Over-Current Protection (OCP) functions help keep the system from being over-stressed and limiting the current to 2A; the power-on reset (POR) functionality further provides a good safety feature. Additionally, the S-8244AAMFN-CEMT2G has other features such as a buck converter with up to 96% efficiency, low quiescence current (down to 0.2mA), auto-sleep mode (down to 10nA consumption), and a wide operating temperature range.

The S-8244AAMFN-CEMT2G can be used to manage multiple power rails within a single system, including those dedicated to battery applications. These power rails can be accurately measured using the integrated 16-bit analogue-to-digital converter (ADC) and DAC converter. This 16-bit resolution ensures a precise measurement and better accuracy for monitoring the battery’s state of charge (SOC), total charge (Qtot) and maximum charge (Qmax). Additionally, the integrated load switch can be used to route the power rails to different sensors and to the battery. This flexibility allows the S-8244AAMFN-CEMT2G to be used in different applications such as mobile phones, digital cameras, battery chargers, and so on.

The S-8244AAMFN-CEMT2G’s battery management working principle operates similar to a precision amplifier stage and controls the voltage on the positive/negative power rails. With the help of a dedicated battery management controller and a microcontroller, this energy management IC can precisely regulate the battery’s charge levels and balance the charge between multiple cells. This helps improve the lifetime of the battery, extends battery runtime and increases safety. Furthermore, the S-8244AAMFN-CEMT2G can be used to measure and report battery capacity, voltage, and other information through various communication interfaces such as I2C and CAN.

The S-8244AAMFN-CEMT2G’s wide-ranging features and innovative design make it an ideal choice for applications in the field of battery management. The ability to measure, monitor and control multiple power rails ensures that the system remains stable and efficiently managed. Furthermore, precise current and voltage measurement with an integrated 16-bit analogue-to-digital converter allows for precise and accurate battery control. The S-8244AAMFN-CEMT2G is the perfect choice for satisfying the highest level of battery performance and safety needed in today’s digital and portable technology applications.
