DescriptionThe TP2216DAP 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. This TP2216DAP allows the distribution of 3.3-V, 5-V, and/ or 12-V power to the card. The current-limiting
feature eliminates the need for fuses. Current- limit reporting can help the user isolate a system fault.
The TP2216DAP features a 3.3-V low-voltage mode that allows for 3.3-V switching without the need for 5-V power. This feature facilitates low-power system designs such as sleep modes where only 3.3 V is available. This TP2216DAP also has the ability to program the xVPP outputs independent of the xVCC outputs. A standby mode that changes all output-current limits to 50 mA (typical) has been incorporated.
End-equipment applications for the TP2216DAP include: notebook computers, desktop computers, personal digital assistants (PDAs), digital cameras, and bar-code scanners.
The TP2216DAP is backward-compatible with the TPS2202A and TPS2206.
