TPS2205 具有并行接口的 1A 双槽 PC 卡电源开关
TPS2205 描述
The TPS2205 PC Card power-interface switch provides 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 a single integrated circuit (IC), 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.
The TPS2205 is backward compatible with the TPS2201, except that there is no VDD connection. Bias current is derived from either the 3.3-V input pin or the 5-V input pin.
