TI rolls single-cell, dual-input Li-Ion battery charger family

Texas Instruments is offering a battery charger chip that support higher cell capacity batteries and increasing battery charge currents of tablets, e-readers and smartphones.

The 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 highlights:

• 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.
• 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 help to provide safe and accurate battery operation.

Pricing: Starts at $3.00 in quantities of 1,000.

Availability: The bq2416x battery chargers are available now in a 49-pin WCSP package;
