Charger IC Lithium Ion/Polymer 29-VQFN-HR (4x4) The BQ25792 is a fully integrated switch-mode buck-boost charger for 1-4 cell Li-ion batteries and Li-polymer batteries. The integration includes 4 switching MOSFETs (Q1, Q2, Q3, Q4), input and charging current sensing circuits, the battery FET (QBAT) and all the loop compensation of the buck-boost converter. It uses NVDC power path management, regulating the system slightly above the battery voltage without dropping below a configurable minimum system voltage. When system power exceeds the input source rating, battery supplement mode supports the system without overloading the input source. BQ25792 supports the full input and output (OTG) voltage ranges for USB Type-C™ and USB power delivery (USB-PD) applications. • High power density, high integration buck-boost charger for 1-4 cell batteries supporting any USB PD 3.0 profile – Integrates four switching MOSFETs, BATFET – Integrates input and charging current sensing • Highly efficient – 750-kHz or 1.5-MHz switching frequencies – 5-A charging current with 10-mA resolution • 96.5% efficient: 16-V battery at 3A from 20V • Supports a wide range of input sources – 3.6-V to 24-V wide input operating voltage range with 30-V absolute maximum rating – Maximum power tracking with input voltage dynamic power management (VINDPM) up to 22 V and input current dynamic power management (IINDPM) up to 3.3 A – Detects USB BC1.2, SDP, CDP, DCP, HVDCP and non-standard adapters • Dual-input power mux controller (optional) for source selection • Narrow voltage DC (NVDC) power path management • Powers USB port from battery (USB OTG) – 2.8-V to 22-V OTG output voltage with 10-mV resolution to support USB-PD PPS – OTG output current regulation up to 3.32 A with 40-mA resolution • Flexible autonomous and I2C mode for optimal system performance • Integrated 16-bit ADC for voltage, current, and temperature monitoring • Low battery quiescent current – 21 µA for battery only operation – 600 nA in Charger Shutdown Mode • High accuracy – +0.65% to -0.85% charge voltage regulation for 2S-4S batteries – ±5% charge current regulation – ±5% input current regulation • Safety – Thermal regulation and thermal shutdown – Input/battery OVP and OCP – Converter MOSFETs OCP – Charging safety timer • Package – 29-Pin 4 mm × 4 mm QFN #CommonPartsLibrary #IntegratedCircuit #PowerManagement #Battery-Charger
