Description
General part information
BQ50002 Series
The bq50002 is a highly integrated wireless power transmitter analog front end that contains all of the analog components required to implement a WPC compliant 5-V transmitter. bq50002 integrates a full-bridge power driver with MOSFETs, variable-frequency oscillator, two-channel communication demodulator, linear regulator, and protection circuits. bq50002 must be used together with the digital controller bq500511 to realize a compact two chip wireless power transmitter solution. The bq500511 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. In order to do this, the bq50002 measures the input DC current very accurately using a current sense amplifier. Should any abnormal condition develop during power transfer, the bq500511 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 bq50002 is available in a thermally enhanced 5.00 mm × 5.00 mm, 32-pin QFN package.
