TI releases WCSP packaged 93% efficient wireless charger IC

Texas Instruments Incorporated has introduced its wireless power receiver IC for designing wireless charging of portable consumer devices, such as smart phones, gaming systems, digital cameras, and medical and industrial equipment.

The bq51013 receiver integrated circuit (IC) combines voltage conditioning and full wireless power control in a small 1.9-mm x 3-mm WCSP package. The new circuit supports up to 5 W of output power, provides up to 93-percent efficient AC/DC power conversion and is the only IC required between the receiver coil and system.

"Smartphone and consumer electronics manufacturers are demanding wireless power, and TI is well positioned to help our customers drive widespread adoption of this technology that makes life easier for people on the go to charge their devices," said Sami Kiriaki, senior vice president over TI's Power Management business. "Designers can use the bq51013 to quickly integrate wireless power into existing and new applications with minimal impact to overall solution size."

The receiver and its associated bq500110 transmitter IC are Wireless Power Consortium (WPC) Qi-compliant. This compliance ensures interoperability between various charging pads and portable devices. Has built-in protection against voltage, current and temperature fault conditions, assures safe and reliable system operation.

Availability: Now
Pricing: Priced at $3.50 in quantities of 1,000.
