PRODUCTION DATA. bq24160, bq24160A, bq24161 bq24161B, bq24163, bq24168 SLUSAO0G – NOVEMBER 2011 – REVISED DECEMBER 2015 bq2416xx 2.5A, Dual-Input, Single-Cell Switched-Mode Li-Ion Battery Charger with Power Path Management and I2C Interface 1 1 Features 1 • High-Efficiency Switched-Mode Charger with Separate Power Path Control – Instantly Start Up System from a Deeply Discharged Battery or No Battery • Compatible with MaxLife™ Technology for Faster Charging When Used in Conjunction With bq27530 • Dual Input, Integrated FET Charger for up to 2.5-A Charging – 20-V input rating, with Overvoltage Protection (OVP) – 6.5 V for USB Input up to 1.5 A – 10.5 V for IN input (bq24160, bq24160A, bq24161, bq24163) up to 2.5 A – 6.5 V for IN input (bq24168) up to 2.5 A • Safe and Accurate Battery-Management Functions – 1% Battery Regulation Accuracy – 10% Charge Current Accuracy • Charge Parameters Programmed Using I2C Interface • Voltage-Based, NTC Monitoring Input – JEITA Compatible (bq24160, bq24160A, bq24161B, bq24163, bq24168) • Available in small 2.8-mm × 2.8-mm 49-ball WCSP or 4-mm × 4-mm VQFN-24 Packages 2 Applications • Handheld Products • Portable Media Players • Portable Equipment • Netbook and Portable Internet Devices 3 Description The bq24160, bq24160A, bq24161, bq24161B, bq24163, and bq24168 are highly integrated single- cell Li-Ion battery charger and system power path management devices targeted for space-limited, portable applications with high-capacity batteries. The single-cell charger has dual inputs which allow operation from either a USB port or a higher-power input supply (that is, AC adapter or wireless charging input) for a versatile solution. The two inputs are fully isolated from each other and are easily selectable using the I2C interface. The power path management feature allows the bq2416xx to power the system from a high-efficiency DC-DC converter while simultaneously and independently charging the battery. The power-path management architecture enables the system to run with a defective or absent battery pack and enables instant system turnon even with a totally discharged battery or no battery. Device Information PART NUMBER PACKAGE BODY SIZE (NOM) bq2416xx VQFN (24) 4.00 mm × 4.00 mm DSBGA (49) 2.80 mm × 2.80 mm (1) For all available packages, see the orderable addendum at the end of the datasheet. 4 Application Schematic |
