RT1985 提供理想二极管反向电流阻断功能,具备低正向压降以及可用于断开控制的使能输入。其 3.4V 至 23V 的输入工作范围及 8A 连续电流额定值,使其非常适合多端口 USB-C Sink 电流应用。此外,本产品具备 28V 绝对最大额定值(AMR)、20A 峰值电流能力(最长 10ms)、欠压锁定(UVLO)、过压保护(OVP)以及过温保护(OTP)功能。可调式软启动电路可设定输出电压上升速率,并管理大电容负载的浪涌电流。在此期间亦提供短路保护功能,而内置 MOSFET 可实现低正向压降及高安全工作区域(SOA)性能。RT1985 采用 VDFN-12TL 3x3 封装,结温工作范围为 -40°C 至 125°C。
