PMIC - Battery Management: S-8232AEFT-T2-G Application Field And Working Principle

The S-8232AEFT-T2-G battery management system is a high-performance power management integrated circuit (PMIC) that is specifically designed to provide over-voltage protection, over-current protection and thermal protection features for lithium-ion battery packs in consumer and industrial devices. This PMIC supplies a highly integrated power conversion and management solution, which offers low-power operation, wide input power range and excellent efficiency.

The S-8232AEFT-T2-G is a highly integrated system capable of managing andmonitoring up to 8 cells in series. This PMIC includes a high accuracy measurement of cell voltage and temperature, fail-safe protection, backup charge and discharge channels, current sense, adjustable charge and discharge voltage and current thresholds, and greatly reduced external component count and complexity. This makes it a very efficient, low-cost and reliable solution for the power management of batteries in smartphones, cameras, tablets, medical and industrial devices.

The main features of the S-8232AEFT-T2-G PMIC include: Wide Input Voltage Range, Ultra-Fast Protection with <100ns Response Time, High-Current Charging, Cell Balancing and Backup Charge/Discharge Channels, Over-Voltage and Over-Current Protection, Adjustable Charge and Discharge Voltage/Current Thresholds, and Temperature and Other Measurements. The PMIC also features a low power standby state and is designed to protect the battery cell and the system itself against thermal and operational abuse.

The S-8232AEFT-T2-G provides wide input voltage range, accommodating a lithium-ion battery pack of 6 cells (2.5 to 4.2V) through 8 cells (3.2 to 4.2V). This allows the PMIC to draw the maximum amount of power from the battery while still protecting the system from over-voltage and over-current conditions. The fast protection speed of the S-8232AEFT-T2-G is only <100ns, achieving reliable protection even in the most abusive conditions. The PMIC also includes significant over-current and over-voltage protection levels that can be adjusted to meet individual applications’ requirements.

The S-8232AEFT-T2-G also includes a high-current charging channel (up to 2A) for rapid charging of the battery packs. And the cell balancing feature can adaptively balance the cells in the battery pack and ensure a reliable, long-term operation. In addition, the PMIC includes a simple backup charge channel and discharge channel to provide extra capacity or power to the battery pack when needed.

The S-8232AEFT-T2-G also features temperature and other measurements, allowing the user to monitor and verify the health of the battery pack. This enhanced temperature and cell voltage measurement capability of the PMIC provides additional safety to the system and improves performance by helping to maintain optimal battery operation.

The S-8232AEFT-T2-G is an ideal solution for managing and monitoring lithium-ion battery packs in consumer and industrial applications. Its features of wide input voltage range, highly integrated solution, high accuracy measurements, fast protection, and low power standby mode make it a highly reliable and efficient PMIC for battery management applications.
