bq50002
Overview
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 fullbridge power driver with MOSFETs, variablefrequency 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.
