资 源 简 介
The TPS2206 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 by means of the P2C (PCMCIA Peripheral-Control) Texas Instruments nonproprietary serial interface. The current-limiting feature eliminates the need for fuses, which reduces component count and improves reliability.
The TPS2206 is backward compatible with the TPS2202 and TPS2202A, except that there is no VDD connection. Bias current is derived from either the 3.
