DESCRIPTION TPS2220A, TPS2223A TPS2224A, TPS2226A SLVS428E – MAY 2002 – REVISED MSRCH 2008 www.ti.com CARDBUS POWER-INTERFACE SWITCHES FOR SERIAL PCMCIA CONTROLLERS • Notebook and Desktop Computers 234 • Provides S-CARD and M-CARD Power Management for CableCARD™ Applications • Bar Code Scanners • Digital Cameras • Single-Slot Switch: TPS2220A Dual-Slot Switches: TPS2223A, TPS2224A, • Set-Top Boxes TPS2226A • PDAs • Fast Current Limit Response Time • Fully Integrated VCC and VPP Switching for 3.3 V, 5 V, and 12 V (no 12 V on TPS2223A) • Meets Current PC Card™ Standards • V pp Output Selection Independent of VCC • 12-V and 5-V Supplies Can Be Disabled • TTL-Logic Compatible Inputs • Short-Circuit and Thermal Protection • 24-Pin HTSSOP, 24- or 30-Pin SSOP • 140-µA (Typical) Quiescent Current from 3.3-V Input • Break-Before-Make Switching • Power-On Reset • –40°C to 85°C Operating Ambient Temperature Range The TPS2223A, TPS2224A, and TPS2226A CardBus™ power-interface switches provide an integrated power-management solution for two PC Card sockets. The TPS2220A is a single-slot option for this family of devices. 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. A faster maximum current limit response time is the only difference between the TPS2223A, TPS2224A, and TPS2226A and the TPS2223, TPS2224, and TPS2226. 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. Shutdown mode is now supported independently on SHDN as well as in the serial interface. Optimized for lower power implementation, the TPS2223A does not support 12-V switching to VPP.
