The BQ24163YFFR battery charger is a sample integrated circuit solution specifically developed for the rapid charging of single cell-Lithium-ion batteries. This system operates in three modes: boost, constant current, and constant voltage. This system-on-chip (SoC) is optimized to deliver a very low system power of less than 3mW, a high efficiency of over 95% , fast charging speeds, and low parts count.

The BQ24163YFFR is a PMIC battery charger that supports either a cell phone\'s external USB port charging or an on-board USB port charging using a standard USB cable. It features a thermally regulated charge current, automatic input current regulation and is designed to be compliant with USB power delivery (PD) standards.

This PMIC battery charger also has active power path control, input current monitoring, and output voltage monitoring. It also provides power factor correction (PFC) for greater power efficiency and improved noise immunity.

The BQ24163YFFR has two main power paths, one for charging and one for the system. The charger IC dynamically charges and maintains an indicating cell voltage by communicating with the system controller. The power path is automatically enabled and disabled based on system loading. The charger IC can also communicate with the system controller to set the optimal charging current level.

This charge IC also features a low quiescent current mode, which allows low system power to be maintained even when the device is not charging. The quiescent current mode is enabled when the voltage of the battery drops below a certain value, allowing the system to enter a low power mode.

In addition to the low quiescent current mode, the BQ24163YFFR also features integrated protection features, including over-current protection, input over-voltage protection, battery reverse protection, and thermal protection. These measures ensure greater safety and reliability during charging operations.

The BQ24163YFFR is ideal for mobile phones, tablets, personal digital assistants (PDAs), digital cameras, and other portable consumer electronics applications. This PMIC-battery charger is designed to reduce the system cost, board area, power consumption, and the number of external components.
