TPS2220B 单 PC 卡串行接口电源开关
TPS2220B 描述
The TPS2220B power-interface switch provides an integrated power-management solution for single Card sockets. The device allows the controlled distribution of 3.3 V, 5 V, and 12 V to one 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 TPS2220A this device supports independent VPP/VCC switching. The TPS2220B is pin compatible with the TPA2220A execept for pin 20 of the TPS2220B which has no connection.
