e-Reader Launches Industry's First Single-Cell, Dual-Input Lithium-Ion Battery Charging IC Family for Smartphones
Published2012.01.19 10:26Supports extended current charging requirements for longer operating time with flexible IC
TI Korea ( www.ti.com/ww/kr ) January 19, 2012 – TI announced the bq2416x family of battery charging ICs capable of supporting higher capacity batteries and increased battery charging currents for devices such as tablets, e-readers, and smartphones. This highly integrated single-cell lithium-ion battery charging IC provides dual inputs, allowing charging via a USB port or a higher power input supply (AC adapter, wireless power input). The two inputs are completely independent of each other and can be easily configured via an I2C interface or a standalone interface. (For more information and to order the bq2416x, please refer to www.ti.com/bq2416x-pr )
Key Features and Advantages
• The integrated FET supports charging rates up to 2.5A (10.5W) from the IN input and up to 1.5A from the USB input.
• AC adapter and USB 2.0/3.0 compatible dual source inputs provide flexibility for design and application.
• The D+/D- automatic adapter for USB input simplifies system design and reduces the number of external components.
• The 20V input with 10.5V overvoltage protection supports low-cost non-rectifying adapters and poor USB sources
• The integrated Power Path Management system supports system startup under over-discharged or no-battery conditions.
• BC1.2 compliance, JEITA charging support, temperature control protection, etc., enable safe and accurate battery operation.
