R5534V

May. 2005 R5534V PCMCIA Power Controller sDESCRIPTION The R5534V switches between the three VCC voltages (0V/3.3V/5.0V) and the VPP voltages (off/0V/3.3V/5.0V). The R5534V has two sets of VCC output and VPP output each, therefore it fits dual slot models. If VCC pin or VPP pin may be clamped to the GND, short current limit works at 1A(Min.) for VCC and 0.15A(Min.) for VPP. The R5534V is suitable for standard PCMCIA power controllers. z Low www.DataSheet4U.com z z z z z z sFEATURES on resistance P-channel MOSFET Switch Dual Slot Power Supply Control Over- Current Limit Protection Thermal Shutdown Protection Low Consumption Current Break-Before-Make Switching SSOP-20 pin Package sAPPLICATIONS Dual Slot PC card Power Supply Pin Voltage Switch Card-bus Slot Power Supply Control PC Card Reader/Writer s PIN CONFIGURATION AVCC5_EN AVCC3_EN AEN1 AEN0 TST VCC5IN AVCCOUT AVCCOUT AVPP OUT VCC3IN 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 BVCC5_EN BVCC3_EN BEN1 BEN0 GND VCC5IN BVCCOUT BVCCOUT BVPP OUT VCC3IN *Note: Same name pins should be connected one another.
