for WPC V 1.2 A11 Transmitters
1 Features 3 Description 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 according to WPC v1.2
specification. 1 5-V Transmitter AFE Compatible with Wireless
Power Consortium (WPC) V1.2 A11 Low Power
Transmitter Specification
Designed to be used with bq500511 WPC …
