The BQ24092DGQR is a single-chip integrated synchronous rectification buck-boost charger designed to meet the needs of the ever-evolving power management industry. It is an IC designed by Texas Instruments to provide efficient and precise charging of a single-cell Li-ion battery pack. This device is suitable for applications such as mobile phones, digital cameras, PDAs, portable gaming systems, and many more.
The BQ24092DGQR provides full charging cycle support via a simple and optimum system design. The IC implements a synchronous buck-boost topology along with a minimum number of external components, resulting in a low BOM cost and exceptional efficiency and accuracy. The device\'s high integration level significantly reduces external parts count, including power and ground connections, as well as number of connections to system controllers and other components.
The BQ24092DGQR supports a wide input voltage range of 2.7 V to 10 V. With this wide range, it is suitable for applications such as automotive and industrial, where the input voltage can vary. The IC also features a high-accuracy voltage and current protection circuitry, programmable impedance, and programmable flash requirements. In addition, the IC includes a programmable LED blink LED to provide visual indication of charge status.
The BQ24092DGQR utilizes a constant-frequency synchronous rectifier control scheme and a buck-boost topology control to achieve high efficiency power conversion for a single-cell Li-ion battery. The synchronous rectifier control reduces power losses by driving the high-side switch at the same frequency of the low-side switch, thus eliminating input current ripple and maximizing a conversion efficiency. The buck-boost topology is employed to improve system flexibility by allowing a flexible input voltage range and to maximize the battery life by preventing overcharging of the battery.
The BQ24092DGQR can be operated in standalone mode, which provides an optimized charging solution without microcontroller. It also provides an an adjustable charge current up to 1.5 A with 200 mV resolution and adjustable end-of-charge voltage with 0.00625 V resolution. The device features thermal regulation and safety loop protection to protect its operation from over-temperature and other dangerous conditions. The device also supports OTG (On-The-Go) mode for short circuit protection, power transfer, and various other applications such as USB-C PD support.
The BQ24092DGQR is an ideal device for various highly integrated portable applications, providing high accuracy and optimization of the charge operation with a minimum of external components. It is an excellent choice for charging of single-cell Li-ion batteries with a wide range of input voltages and high efficiency operation while maintaining a compact form factor. The IC\'s robust protection features are designed to ensure a safe operation and to ensure system reliability.
