过压保护 IC

RT9718 是避免低压系统受到异常高压冲击的集成电路，最高可以耐受 30V 电压。它通过监视输入电压、电池电压和充电电流并确保所有参数都在正常工作范围内来确保安全。当输入电压超过预设 OVP 阈值时，它可在 1μs 内断开 MOSFET ，以便在任何危害发生前就将电源供应断开。它可在没有电池存在的情况下提供电压输出。流过功率 MOSFET 的电流是受限的，目的是避免以过大的电流对电池进行充电，电流限制参数可通过 ILIM 和 GND 之间的电族进行设定。OCP 功能的实施电路中包含了一个4位的计数器，当过流事件被计数到16次时，MOSFET 功率开关被彻底关断，仅在重新上电以后才能恢复。RT 完整集成多重保护措施►可调过流保护►输入过压保护►电池过压保护\n最高承受 30V 输入电压\n过压断开时间小于 1μs\n保护阈值精度高\n过热保护\n瞬态期间误触发消除能力强\n警告指示输出\n使能控制\n热性能加强的 WDFN 封装\n符合 RoHS 规范，不含卤素;
