1.5A USB-Friendly Li-Ion Battery Charger and Power-Path Management IC with 4.2 VBAT The BQ24075TRGTR (from Texas Instruments) is a highly integrated single-cell Li-Ion / Li-Polymer linear battery charger IC with power-path management. It is designed for portable and space-constrained applications, allowing a device to be powered from a USB port or AC adapter while simultaneously charging the battery. The device integrates charging control, power-path management, and safety features into a compact package. A key feature is its Dynamic Power Path Management (DPPM), which ensures the system is powered even when the battery is low or absent, while intelligently managing charging current. Key Features Battery Charging Supports single-cell Li-Ion / Li-Polymer batteries Up to 1.5 A programmable charge current Three-phase charging: Pre-charge (conditioning) Constant current Constant voltage Fixed 4.2 V charge voltage Power Path Management Dynamic Power Path Management (DPPM): Powers system and charges battery simultaneously Prioritizes system load over charging Allows system operation even with: Deeply discharged battery No battery connected Input & Power Features Operates from: USB input (100 mA / 500 mA selectable) AC adapter Programmable input current limit up to 1.5 A Input voltage range: ~4.35 V to 6.4 V (28 V max rating) Input dynamic power management (VIN-DPM) prevents source overload Protection & Safety Thermal regulation and shutdown Over-voltage protection (OVP) Short-circuit and reverse current protection Battery temperature monitoring (NTC thermistor input) Battery disconnect (SYSOFF) feature Control & Status Standalone operation (no MCU required, resistor-programmable) Charge status outputs: Charging Charge complete Power good Physical Characteristics Package: 16-pin VQFN (3 mm × 3 mm) Operating temperature: –40°C to +85°C #commonpartslibrary #integratedcircuit #powermanagement #batterycharger

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
