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.
