The transmitter circuit is designed for 5 V systems, allowing the charging pad to be securely combined with devices that comply with the Wireless Power Consortium (WPC) Qi standard, such as smartphones or other portable electronic devices, to receive packet communications and to efficiently manage power transmission. In addition, the bq500211 uses TI Dynamic Power LimitTM technology to optimize the effective power of a limited power supply.
Features and benefits of the bq500211:
· Improved user experience: The first integrated transmitter circuit allows consumers to plug a wireless power strip into any USB port or 5V power system;
· Wireless power transmission intelligent control: TI Dynamic Power Limit technology optimizes the effective power of the limited input power supply;
· Save board space: This circuit can be used as a WPC A5 transmitter that supports magnetic positioning guidance, or as an A11 transmitter that does not require magnetism;
· Fault detection for improved reliability: The integrated charge status mode and fault indication feature alert the user to any abnormal conditions during power transfer.
TI and wireless power
TI's line of wireless power ICs helps design engineers get the most out of their imaginations, developing innovative and efficient wireless charging capabilities for smartphones, tablets and other portable electronics, as well as designing wireless charging power supplies from charging boards to cars and furniture. Power requirements. The TI bq5101x integrated receiver provides regulated DC output and digital control feedback for the transmitter, while the TI bq500xx Series wireless power transmitter efficiently manages the receiver's power transfer.
Availability and packaging
The new bq500211 wireless power transmitter is available in a 48-pin, 7 mm × 7 mm QFN package. Volume production is now available and can be ordered through TI and its worldwide network of authorized distributors.
