充電時系統(tǒng)安全保護器

RT9730是設計用于替代充電系統(tǒng)中的靜態(tài)元件以實現(xiàn)保護功能的 IC ，可確保低壓系統(tǒng)免受高達 28V 的電壓侵害。它對輸入電壓進行監(jiān)控以確保所有元件都工作在正常的參數范圍內，它也對自身溫度進行監(jiān)控以確保在自身溫度超過 140°C 時關斷 MOSFET。當輸入電壓超過默認的閾值時，IC 將在 1μs 內斷開 MOSFET 以移除電源，確保不會發(fā)生損害事件。用戶可以通過 CHRIN 端子對輸入電壓狀況進行監(jiān)控，該端子的驅動能力達 50mA 。假如工作環(huán)境的所有參數都在正常范圍內，外部充電器可通過 GATDRV 端子對 P-MOSFET 的柵極進行控制。RT9730 以 WDFN-8L 2x2 的 ? 不需外部阻斷二極管\n? 高精度過壓保護閾值\n? 高瞬態(tài)沖擊誤觸發(fā)抑制能力\n? 符合 RoHS 規(guī)范，不含鹵素;
