APPLICATION INFORMATION
General Overview of a Wireless Power System
Figure 8 shows a block diagram of a wireless power system, which consists of a transmitter and receiver. The
transmitter consists of an ac-dc power stage, followed by a transmitter coil driver, coil voltage, and coil current
sensing block, and a wireless power controller (BQ500110). The receiver consists of a receiver coil, rectifier,
BQ25046 voltage regulation circuit, and MSP430BQ1010 wireless power controller. The output of the system is
the BQ25046 5-V regulated output voltage that is used as a power supply to the charger in a cellular phone or
other mobile device.
The system shown in Figure 8 implements wireless power transfer via inductive coupling between the transmitter
and receiver. In this system, the transmitter drives a transmit coil with a frequency between 100 and 200 kHz,
and the receiver coil, which is in close proximity to the transmitter coil, rectifies the received voltage to power the
BQ25046. In addition, the receiver continuously monitors its operating point (coil voltage and coil current) and
communicates correction packets to the transmitter via backscatter modulation.

Using MSP430BQ1010 in a Wireless Power System
Figure 9 shows the MSP430BQ1010 used in a wireless power receiver solution. In this application, a receiver coil
connects to a half-synchronous rectifier that includes a rectifier filter capacitor. The rectifier voltage is connected
directly to the IN pin of the BQ25046, and the BQ25046 generates a 3.3-V LDO output that is used to power the
MSP430BQ1010 wireless power supply controller. The MSP430BQ1010 monitors the rectifier voltage and output
current and communicates to the transmitter via the communication modulator to optimize the power delivered to
a mobile device. The OUT pin of the BQ25046 delivers 5-V to a mobile device at power levels up to 5 W.
