The BQ24210DQCR battery charger, is an integrated power management IC specifically designed for WLCSP designs, targeted mainly at USB-C phone chargers and other portable devices requiring low component count. It features a compact 11-pin WLCSP package, buck and boost converters, autonomous buck and boost switching, a wide input voltage range, integral TFT display and advanced safety features, as well as supporting multiple charging profiles and autonomous load switch control.

The BQ24210DQCR is designed to expand the power management options available to designers of USB Type-C powered devices. It meets the needs of today\'s ever-shrinking size constraints, while offering enhanced power management capabilities and advanced safety features. The BQ24210DQCR is suitable for use in portable applications such as smartphones, tablets, and laptop power supplies, as well as a range of other applications. It supports charging from input sources ranging from 3.2V to 12V, allowing for a wide range of input power options. It supports autonomous buck and boost switching, allowing the device to intelligently adjust the charging voltage and current to best suit the application.

The BQ24210DQCR can be used to enable quick charging of battery packs from low input voltages from as low as 3.9V. It can supply up to 6A of charging current and is capable of charging a battery at up to 6.1A. The charging process is controlled by a configurable set of parameters including the set point voltage, currents, “Fast Charge” and “Trickle” settings. The charger also supports autonomous switching between buck and boost modes to ensure optimal charging is achieved. In addition, the charger supports autonomous load switch control, allowing it to switch on and off loads such as displays or backlight sources.

The BQ24210DQCR has multiple safety features to ensure safe and reliable operation with any connected battery pack. It can automatically detect and adjust to the incorrect connection of polarity and the device also monitors for overvoltage, undervoltage, overcurrent, and over temperature conditions, and can shut down the charging process if necessary. It also features a unique “AutoSafe” protection feature which will shut down the charger if the capacity of the connected battery pack is lower than the programmed minimum charge capacity. The charger also features an internal TFT display which can be used to monitor the charging process and can provide information such as charging profile and current charge.

In summary, the BQ24210DQCR is an ideal choice for portable device designers requiring enhanced power management capabilities in a small and low-cost integrated package. Its wide input voltage range and autonomous buck and boost switching make it well suited to a range of applications, while its advanced safety features ensure reliable and safe operation. The BQ24210DQCR is ideal for use in small scale applications that require small component counts and a wide range of power management features.
