【产品】高度集成、单芯片的无线充电接收器P9221-R,适用于15W应用
IDT(RENESAS收购)推出的P9221-R是一款高度集成,符合Qi标准适用于15W应用的无线电源接收器。采用磁感应充电技术,接收器将来自谐振回路的交流电源信号转换为9V或12V直流输出电压。集成的低RDS(ON)同步整流器和超低压差稳压器提供高效率,使其成为电池供电应用的理想选择。
该接收器包含一个32位ARM Cortex®-M0处理器,具有高级可编程性。该器件输出专有的对准引导,以实现接收器和发送器之间的最佳耦合,并具有可编程电流限制。创新的过压保护方案无需额外电容,从而最大限度地减少了外部元件数量和成本。P9221-R与P9242-R发送器一起,是一款适用于15W应用的完整无线电源系统解决方案。P9221-R采用节省空间的2.64×3.94 mm 52-WLCSP封装。 额定工作温度范围为0°C至85°C环境温度。
P9221-R的特点
•单芯片,15W无线电源接收器
•符合WPC 1.2.2标准
•无需外部电容器实现过压保护
•使用P9242-R Tx可实现87%的DC-DC效率峰值

【应用】无线充电接收器P9221-R应用于安卓平板电脑,与发射端配合测试DC/DC效率可高达87%
本文介绍了IDT(Renesas收购)无线充电接收器P9221-R在安卓平板电脑中的应用。目前市场上带有无线充电设计的智能终端越来越多,无线充电功能已日渐成为各类终端产品的标准配置。经过一系列调研,我们发现市面上大多数的无线充电板(即发射端TX)均采用IDT方案,这给我们的无线充电接收方案选择带来了启示,因此在8寸平板电脑进行无线充电方案选型时我们把选型范围锁定在了IDT的产品P9221-R上。
