TPS2221 具有串行接口的 1A 双槽 CardBay PC 卡电源开关

TPS2221 描述

The TPS2228 and TPS2221 PC card power interface switches provide an integrated power management solution for both dual and single PC card sockets. The TPS2228 is a dual-slot power interface switch for serial PCMCIA controllers. The TPS2221 is a single-slot power interface switch for parallel PCMCIA controllers. These power interface switches support the distribution of 3.3 V, 5 V and 1.8 V to the PC card slot while providing current-limiting protection with overcurrent reporting.
