BQ25872YFFR

The BQ25872YFFR is a System Load Protection/System Power Path Management (SLPM/SPPM) integrated circuit (IC) from Texas Instruments, with a USB Type-C or USB-PD-compliant fast-charging solution (3.5 A) tailored specifically for USB Power Delivery (PD). It combines an SLPM controller with the features of an SPPM controller to provide an efficient charging power path for USB-PD compatible products, such as laptops and tablets, using a single chip.

The BQ25872YFFR is designed to provide an efficient charging solution to products that require a fast-charging solution and draws power from a USB Type-C or USB-PD-compliant source. It is suitable for application in laptops, gaming consoles, tablets and other products that require fast power delivery and PD compliance.

The BQ25872YFFR is based on a Texas Instruments’ proprietary SLPM/SPPM architecture. SLPM stands for System Load Protection/System Power Path Management; this enables the IC to manage incoming power from a USB Power Delivery source. The IC is configured as a primary power source, and is capable of switching between one or more power sources, as defined in its configuration. The IC is also capable of autonomously managing the power delivery path, and determining the most efficient way to send power to the system.The system requires a 3.5 A USB-PD source to provide enough current to the system load, while ensuring PD compliance. The IC is capable of detecting the presence of a power source and automatically engaging the power source to provide power to the system.The BQ25872YFFR also features system protection features to protect the system against power surges and other events. This includes overtemperature protection, overvoltage protection, reverse current protection, and short-circuit protection.Finally, the IC includes a highly robust analog engine that can dynamically and autonomously manage the power delivery path in order to ensure a precise power delivery to the system. This ensures optimal system performance and PD compliance.
