DESCRIPTION
MSP430BQ1010 is an advanced fixed-function
device that forms the control and communications
unit on the receiver side for wireless power transfer in
portable applications. MSP430BQ1010 complies with
the Wireless Power Consortium (WPC) specification.
Together with a WPC-compliant transmitter-side
controller, a complete wireless power system is
enabled.
In a wireless power solution, power is transferred
from the transmitter coil in the charging pad to the
receiver coil embedded in the portable device, based
on near-field magnetic induction. Feedback
information from the receiver is transmitted back to
the transmitter via changes in the reflected
impedance of the receiver device.
The receiver side on the mobile/portable device
consists of a rectification circuit, a voltage-
conditioning unit, and a control and communications
unit. The MSP430BQ1010 device is the control and
communications unit that comprises the digital logic
part of the receiver. This unit executes the relevant
power-control algorithms and protocols, monitors
various voltage and current levels, and provides
feedback to the transmitter via the communications
modulator. MSP430BQ1010 devices are specifically
configured and preprogrammed to be fully compliant
with the Wireless Power Consortium standards. The
Wireless Power Consortium has developed a
standard for wireless charging technology to ensure
interoperability between various primary and receiver
devices.
Wireless Power Consortium (WPC)
The consortium is a cooperation of companies,
including Texas Instruments, that wants to ensure
that the products created are completely
interoperable. MSP430BQ1010, as part of the
wireless charging receiver solution, complies with the
WPC standard.
