Description
General part information
BQ50002A Series
The bq50002A device is a highly integrated wireless power transmitter analog front end (AFE) that contains all of the analog components required to implement a Wireless Power Consortium (WPC) compliant 5-V transmitter. The bq50002A device integrates a full-bridge power driver with MOSFETs, variable-frequency oscillator, two-channel communication demodulator, linear regulator, and protection circuits. The bq50002A device must be used together with the digital controller bq500511A to realize a compact two chip wireless power transmitter solution. The bq500511A safely engages the RX device, receives packet communication from the powered device, and manages the power transfer according to WPC v1.2 specification.
The system supports foreign object detection (FOD) by continuously monitoring the amount of power transferred and comparing that to the amount of received power, as reported by the receiver. This protects against power loss to metal objects misplaced in the wireless power transfer field. To do this, the bq50002A measures the input DC current accurately by using a current sense amplifier. Should any abnormal condition develop during power transfer, the bq500511A handles it and provides indication outputs. Comprehensive status and fault monitoring features enable a low cost yet robust WPC-certified wireless power system design.
The bq50002A is available in a thermally enhanced 5.00 mm × 5.00 mm, 32-pin QFN package.
