Description

The bq5105x device is a high-efficiency, Qi-compliant

wireless power receiver with an integrated Li-Ion/Li-

Pol battery charge controller for portable applications.

The bq5105xB devices provide efficient AC-DC

power conversion, integrates the digital controller

required to comply with Qi v1.2 communication

protocol, and provides all necessary control

algorithms needed for efficient and safe Li-Ion and Li-

Pol battery charging. Together with the bq500212A

transmitter-side controller, the bq5105x enables a

complete wireless power transfer system for direct

battery charger solutions. By using near-field

inductive power transfer, the receiver coil embedded

in the portable device can pick up the power

transmitted by transmitter coil. The AC signal from

the receiver coil is then rectified and conditioned to

apply power directly to the battery. Global feedback

is established from the receiver to the transmitter to

stabilize the power transfer process. This feedback is

established by using the Qi v1.2 communication

protocol. The bq5105xB devices integrate a low-impedance

synchronous rectifier, low-dropout regulator (LDO),

digital control, charger controller, and accurate

voltage and current loops in a single package. The

entire power stage (rectifier and LDO) use low-

resistance N-MOSFETs (100-mΩ typical Rdson) to

ensure high efficiency and low power dissipation.
