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 LinBiCMOS

™ process. The circuit allows the distribution of 3.3-V, 5-V, and/or 12-V card power by

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

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).
