具有振鈴補償?shù)?100mA 音圈電機透鏡驅(qū)動器（適用于攝像頭自動對焦）

DRV201 器件是一款用于攝像機自動對焦的高級音圈電機驅(qū)動器。它有一個用于設定 VCM 電流的集成型數(shù)模轉換器。VCM 電流由一個固定頻率 PWM 控制器或者一個線性模式驅(qū)動器控制。可通過 I2C 寄存器選擇電流生成。DRV201 器件集成有感應電阻以實現(xiàn)電流調(diào)節(jié)，并可通過 I2C 控制電流。\n\n 當改變 VCM 內(nèi)的電流時，鏡頭振鈴由高級振鈴補償功能進行補償。振鈴補償大大減少了自動對焦所需的時間。此器件還有一個 VCM 短路和開路保護功能。 ? 可配置為線性或脈寬調(diào)制 (PWM) 模式 VCM 電流生成方案\n? 高級振鈴補償\n? 保護 \n? 欠壓閉鎖 (UVLO)\n?
