TPS2214A 具有并行接口的 1A 单槽 PC 卡电源开关
TPS2214A 描述
The TPS2214A and TPS2216A PC Card power-interface switches provide an integrated power-management solution for two PC Cards. All of the discrete power MOSFETs, a logic section, current limiting, and thermal protection for PC Card control are combined on single integrated circuits. These low-cost devices allow the distribution of 3.3-V, 5-V, and/or 12-V power to the card. The current-limiting feature eliminates the need for fuses. Current-limit reporting can help the user isolate a system fault.
The TPS2214A and TPS2216A feature a 3.3-V low-voltage mode that allows for 3.3-V switching without the need for 5-V power. This feature facilitates low-power system designs such as sleep modes where only 3.3 V is available
