description
The TPS2202AI 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, thermal protection, and power-good reporting for PC Card control are combined on a single integrated circuit (IC), using the Texas Instruments LinBiCMOSTM 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. Current-limit reporting can help the user isolate a system fault to a specific card. The TPS2202AI incorporates a reset function, selectable by one of two inputs, to help alleviate system errors. The reset function enables PC Card initialization concurrent with host platform initialization, allowing a system reset. Reset is accomplished by grounding the VCC and Vpp (flash-memory programming voltage) outputs, which discharges residual card voltage. End equipment for the TPS2202AI includes notebook computers, desktop computers, personal digital assistants (PDAs), digital cameras, handiterminals, and bar-code scanners. The TPS2202AI is only available taped and reeled (either TPS2202AIDFLE or TPS2202AIDBLE).
