for WPC v1.2 A11 Transmitters
1 Features 3 Description 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 …
