具有振铃补偿的 100mA 音圈电机透镜驱动器（适用于摄像头自动对焦）

DRV201 器件是一款用于摄像机自动对焦的高级音圈电机驱动器。它有一个用于设定 VCM 电流的集成型数模转换器。VCM 电流由一个固定频率 PWM 控制器或者一个线性模式驱动器控制。可通过 I2C 寄存器选择电流生成。DRV201 器件集成有感应电阻以实现电流调节，并可通过 I2C 控制电流。\n\n 当改变 VCM 内的电流时，镜头振铃由高级振铃补偿功能进行补偿。振铃补偿大大减少了自动对焦所需的时间。此器件还有一个 VCM 短路和开路保护功能。 • 可配置为线性或脉宽调制 (PWM) 模式 VCM 电流生成方案\n• 高级振铃补偿\n• 保护 \n• 欠压闭锁 (UVLO)\n• VCM 输出上的开路或短路保护\n• 4kV 静电放电 (ESD) 人体放电模式 (HBM)\n• I2C 接口\n• 6 焊球晶圆级芯片 (WCSP) 封装，焊球间距 0.4mm\n• 封装高度： \n• YMB：0.3mm;
