This new level of performance supports larger form factors,
including the latest smart phones and tablet devices that
require faster charging times. This family adheres to the
Wireless Power Consortium (WPC) and Medium Power
Working Group (MPWG) specification and has the potential
to support other future standards. With such a high level
of integration, the WPR1516 IC will drive smaller printed
circuit board (PCB) form factor designs and offers the
possibility for applications to do thermal design based
on the application requirement.
The WPR1516 IC is based on the ARM
®
Cortex
®
-M0+
core and includes frequency shift keying (FSK) and CNC
features allowing for easy development of bi-directional
communication architecture between a transmitter and
receiver. A PGA handles small signals which can easily detect
the power loss of the system to achieve system-level foreign
object detection (FOD). A USB/Adapter switcher sets the
priority between wired and wireless charging.
The WPC1516 IC is offered in both QFN and WLCSP package
options ideal for both industrial and consumer applications.
