TI introduces industry's first single-cell, dual-input Li-Ion battery charger family for tablets, e-readers and smartphones

The two inputs are fully independent from each other and are easily configurable using the I2C interface or stand-alone interface.

Key features and benefits
• Integrated FETs support charge rates up to 2.5 A (10.5 W) from IN input, and 1.5 A from USB input.
• Dual source inputs, AC adapter and USB 2.0/3.0 compatibility provide flexibility in design and applications.
• D+/D- auto adapter for USB input ease system design and reduce external components.
• 20-V input with 10.5-V over voltage protection supports low-cost unregulated adapters and poor USB sources.
