Charger IC Lithium Ion/Polymer 29-VQFN-HR (4x4) The BQ25792 is a switch-mode synchronous buck-boost charger with full power-path management. It can automatically regulate power flow between the input source, system load, and battery. It supports a wide input range and is designed for USB Type-C™ / USB Power Delivery (USB-PD) systems, enabling both charging and OTG (power output from battery) operation. ⭐ Key Features ⚡ High-performance charging Up to 5 A charge current Supports 1S to 4S battery packs High efficiency (up to ~96% under typical conditions) Programmable switching frequency: 750 kHz or 1.5 MHz 🔋 Wide input support Input voltage range: 3.6 V to 24 V Absolute max rating up to 30 V Supports USB adapters and barrel jack sources Detects USB charging standards (BC1.2, DCP, CDP, HVDCP, etc.) 🔄 Buck-boost power conversion Seamless buck, boost, and buck-boost operation Maintains stable system voltage even when battery is low or input varies 🔌 USB-PD / OTG support USB Power Delivery (PD 3.0 compatible) Supports OTG output (battery powers USB port) OTG voltage range: 2.8 V to 22 V 🧠 Intelligent power management NVDC power path management (system can run without battery) Dual-input power mux controller (select between two power sources) Battery supplement mode (prevents input overload) 📊 Monitoring & control Integrated 16-bit ADC for voltage, current, temperature monitoring Fully I²C configurable Autonomous or host-controlled operation 🛡️ Protection & safety Input and battery over-voltage/over-current protection Thermal regulation and shutdown Charging safety timer MOSFET protection (internal switching FETs included) 📦 Package 29-pin VQFN (4 mm × 4 mm) package Industrial temperature range: -40°C to 85°C #CommonPartsLibrary #IntegratedCircuit #PowerManagement #Battery-charger

The HUSB238A is a highly integratedstand-aloneUSB Type-C® and Power Delivery (PD) Sinkcontroller.The HUSB238A integrates the CClogic, USBPDprotocol and the legacy protocols. The HUSB238A can run in I2C mode andGPIOmode.In I2C mode, an I2C master can access theHUSB238Ato configure settings, read back status andperformadvanced functions such as DRSwap, VDMmessages. The HUSB238A supports APDO, maximum48 V/5 A EPR FPDO and EPR AVSin I2Cmode. While in GPIO mode, the configuration is achievedviathe setting pins. The HUSB238A can beconfiguredtosupport maximum 28 V/3.25 A PDOviaVSETandISET pins, only two resistors are usedtoset thevoltage and current. The ultra-low operation current of theHUSB238Ahelps the system to reduce the total power dissipationand suitable for a battery application. The HUSB238A is available in QFN3 mmx3mm-16Lpackage.
