BQ50002RHBT

Highly integrated wireless power transmitter analogue front end for WPC v1.2 A11 transmitters. The device contains the entire analogue components required to implement a WPC compliant 5V transmitter. It integrates a full bridge power driver with MOSFETs, variable frequency oscillator, two channel communication demodulator, linear regulator and protection circuits. It safely engages the RX device, receives packet communication from the powered device and manages the power transfer according to WPC v1.2 specification. Comprehensive status and fault monitoring features enable a low cost yet robust WPC certified wireless power system design. Typically used in smart phone and wearable application and transmitters.

• Designed to be used with bq500511 WPC controller
• Supports 5W on the receiver output
• Two chip solution enables high efficiency transmitter designs of <gt/>75% efficiency
• Less than 30mW ultra-low standby power (even during digital ping)
• Dynamic Power Limiting (DPL)™ enables operation from inputs sources with limited power
• LED indication of charging state and fault status
• Accurate foreign object detection method (FOD)
