TPS2212 具有并行接口的 0.3A 单槽 PC 卡电源开关
TPS2212 描述
The TPS2212 PC Card power-interface switch provides an integrated power-management solution for a single low power PC Card. All of the discrete power MOSFETs, a logic section, current limiting, and thermal protection for PC Card control are combined on a single integrated circuit, using the Texas Instruments LinBiCMOS™ process. The circuit allows the distribution of 3.3-V, 5-V, and/or 12-V card power, and is compatible with many PCMCIA controllers. The current-limiting feature eliminates the need for fuses, which reduces component count and improves reliability. Current-limit reporting can help the user isolate a system fault to the PC Card.
The TPS2212 features a 3.3-V low-voltage mode that allows for 3.3-V switching without the need for 5 V.
