A battery charger IC from Texas Instruments supports higher cell capacity batteries and the battery charge currents of tablets, e-readers and smartphones. The bq2416x integrated, single-cell, Li-Ion battery charger has dual inputs, for operation from either a USB port or higher power input supply (AC adapter or wireless power input). The two inputs are independent from each other and configurable using the I2C interface or standalone interface. The integrated FETs support charge rates up to 2.5A (10.5W) from IN input, and 1.5A from USB input. The D+/D- auto adapter for USB input reduces external components and the 20V input with 10.5V over-voltage protection supports unregulated adapters and poor USB sources. The integrated power path allows system startup from deeply discharged or no battery power operating conditions.
