May. 2005 R5534V PCMCIA Power Controller DESCRIPTION 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.

Without being VCCOUT=0V, if commanded to immediately switch from 5V to 3.3V or vice versa, enhancement of the second switch begins after the first is OFF, realizing break-before-make protection. In case that an OUT pin may be clamped to the GND, if over-current would continue, the temperature of the IC would increase drastically. If the temperature of the IC is beyond 135C, the switch transistor turns off. Then, when the temperature of the IC decreases equal or lower than 125C, the switch transistor turns on. Unless the abnormal situation of OUT pin is removed or turned off, the switch transistor repeats on and off. Short over-current level is set internally in the IC. There are two types of response against over-current: Under the condition that OUT pin is short or large capacity is loaded, if the IC is enabled, the IC becomes constant current state immediately. Current level of constant current is short current limit. While the switch transistor is on, if OUT pin is short or large capacity is loaded, until the current limit circuit responds, large transient current flows. The transient current depends on the impedance between the power supply circuit, VCC5IN/VCC3IN and load capacitance. In other words, the transient current depends on the transient response characteristics of the power supply circuit, VCC5IN/VCC3IN, PCB layout, and the connector of the card. After the transient current is beyond the current limit threshold and current limit circuit responds, the IC becomes into the constant current mode, and the current level is equal to short current limit. APPLICATION NOTES * VCC5IN voltage should be equal or more than VCC3IN. * Same name pins should be connected one another. * There is a parasitic diode between source and drain of the switch transistors. (Refer to the block diagram.) Therefore, even If the switch may be disabled, in case the OUT voltage is higher than VCC5IN, some current flows from OUT to VCC5IN. * Connect TST pin to Vcc5IN * Set a bypass capacitor with capacitance ranging from 0.1F to 1.0F between VCC5IN pin and GND pin, and between VCC3IN and GND pin each.
