Diodes Incorporated DPS1133电源开关
Diodes Inc. DPS1133电源开关是高压开关,支持USB供电规范版本3.0, V1.1 (USB PD 3.0) 的快速角色互换 (FRS) 功能。该器件在所有USB PD 3.0工业标准电压等级下工作,通常装配在采用得越来越多的USB Type-C™连接器旁边。DPS1133结合了两个非常低RDS(ON)_TYP (≤30mΩ) N-MOSFET开关。这允许最大连续电流高达3.5A。N-MOSFET开关保证在tSrcFRSwap时间内导通,因此VBUS处于USB PD 3.0需要的VSAFE5V 电压等级。综合故障检测和恢复机制(如输入欠压锁定、反向电压和电流阻断、热关断,过校正和短路保护)有助于确保系统完整性。其他功能包括可调DV/DT、电流和电压限制、电流监视器输出和通过板载115Ω电阻器的端口放电。很多参数可通过外部电阻器调节,以实现可用性和灵活性。电源开关采用无卤、无锑、符合RoHS指令的QFN封装。热效率高的QFN封装在工作期间提供足够低的表面温度。该器件的4x4mm小尺寸和0.8mm高度使DPS1133非常适合用于终端系统。应用包括扩展坞、通用和多媒体集线器、FPTV、移动和桌面计算、机器人技术、AR/VR护目镜等。特性
