充电时系统安全保护器

RT9730是设计用于替代充电系统中的静态元件以实现保护功能的 IC ，可确保低压系统免受高达 28V 的电压侵害。它对输入电压进行监控以确保所有元件都工作在正常的参数范围内，它也对自身温度进行监控以确保在自身温度超过 140°C 时关断 MOSFET。当输入电压超过默认的阈值时，IC 将在 1μs 内断开 MOSFET 以移除电源，确保不会发生损害事件。用户可以通过 CHRIN 端子对输入电压状况进行监控，该端子的驱动能力达 50mA 。假如工作环境的所有参数都在正常范围内，外部充电器可通过 GATDRV 端子对 P-MOSFET 的栅极进行控制。RT9730 以 WDFN-8L 2x2 的 • 不需外部阻断二极管\n• 高精度过压保护阈值\n• 高瞬态冲击误触发抑制能力\n• 符合 RoHS 规范，不含卤素;
