TPS2224 具有串行接口且采用 24 引脚封装的 1A 双槽位 PC 卡电源开关
TPS2224 描述
The TPS2223, TPS2224 and TPS2226 Card-BusTM power-interface switches provide an integrated power-management solution for two PC Card sockets. These devices allow the controlled distribution of 3.3 V, 5 V, and 12 V to each card slot. The current-limiting and thermal-protection features eliminate the need for fuses. Current-limit reporting helps the user isolate a system fault. The switch rDS(on) and current-limit values have been set for the peak and average current requirements stated in the PC Card specification, and optimized for cost.
Like the TPS2214 and TPS2214A and the TPS2216 and TPS2216A, this family of devices supports independent VPP/VCC switching; however, the standby and interface-mode pins are not supported
