Texas Instruments introduced a battery charger integrated circuit to support higher cell capacity batteries and increasing battery charge currents of tablets, e-readers and smartphones. The highly integrated single-cell Li-Ion battery charger has dual inputs, which allow operation from either a USB port or higher power input supply (AC adapter or wireless power input). The two inputs are fully independent from each other and are easily configurable using the I2C interface or stand-alone interface.
Key features
Integrated FETs support charge rates up to 2.5A (10.5W) from IN input, and 1.5A from USB input
Dual source inputs, AC adapter and USB 2.0/3.0 compatibility
D+/D- auto adapter for USB input
20-V input with 10.5-V over voltage protection
Integrated power path allows system startup from deeply discharged or no battery power operating conditions
BC1.2 compliance, JEITA charging support and thermal regulation protection
TI offers a variety of tools and support to speed the implementation of the bq2416x family of devices. The bq2416x battery chargers are available now in a 49-pin WCSP package; suggested resale pricing starts at $3.00 in quantities of 1,000.
