引脚
引脚功能描述
(1)LV0&LV1引脚:LV0和LV1是低压驱动脚,用于驱动H桥的两个下管NMOS,两个上管PMOS的驱动信号由H桥自身提供。
(2)LED/OSC引脚:OSC引脚作为异物检测使用,在LED正常驱动期间插入短暂的异物检测。该引脚驱动LED时端口为输出态,在异物检测时端口为输入态。
(3)QII引脚:无线充电通讯数据输入端,内部集成消息解码功能。
应用参考电路
扩展方案
低功率无协议收发方案(适应于3W以内功率传输)
参数
(1)绝对最大值
临界或者超过绝对最大值将可能导致芯片工作不正常甚至损坏。
(2)电气参数
测试条件:TA=25℃。
封装信息
说明:封装信息图中标注的单位均为mm(毫米)。
