物料型号:bq50002A 器件简介:bq50002A是一款高度集成的无线功率发射器模拟前端(AFE),它包含了实现符合无线功率联盟(WPC)标准的5V发射器所需的所有模拟组件。

该器件集成了全桥功率驱动器、MOSFET、可变频率振荡器、两通道通信解调器、线性调节器和保护电路。

bq50002A必须与数字控制器bq500511A一起使用,以实现紧凑的两芯片无线功率发射器解决方案。

引脚分配:bq50002A提供32个引脚,包括供电引脚(如BOOT1、BOOT2、PVIN1、PVIN2)、接地引脚(如GND)、控制引脚(如CSN、CSO、CSP、DMIN1、DMIN2、DMOUT1、DMOUT2、EN、MODE、PGND、PWM_CTRL、PWM1/CLK_IN、PWM2/UP_DN、SW1、SW2)等。

参数特性:工作电压范围为4.5V至5.5V,具有超低待机功耗,即使在数字ping期间也小于30毫瓦。

支持高达75%以上的高效率发射器设计,具有动态功率限制(DPL)功能,可从有限功率输入源操作。

功能详解:bq50002A支持异物检测(FOD),通过连续监测传输的功率并与接收器报告的接收功率进行比较来保护。

它还具有准确的电流感应放大器、可变频率振荡器、高效率电压调节器和高灵敏度解调器,用于解码来自接收器的信号。

应用信息:适用于WPC和专有5V无线功率发射器,如智能手机和可穿戴应用的WPC兼容无线发射器、专有无线充电器和发射器、医疗和可穿戴应用。

封装信息:bq50002A采用热增强型5.00 mm x 5.00 mm,32引脚QFN封装。
