More over, such values for any two or more items of the ratings must not be reached simultaneously. Operation above these absolute maximum ratings may cause degradation or fatal damage to the device. These mean stress ratings and do not necessarily imply functional operation below these limits.

Without being V CCOUT=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 switching". 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 Typ. 135°C, the switch transistor turns off. Then, when the temperature of the IC decreases by approximately 10 °C, 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: (1) Under the condi tion 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. (2) While the switch transistor is on, if OUT pin is short or large c apacity is loaded, until the current limit circuit responds, large transient current flows. The transient current depends on the impeda nce 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.

• Set a bypass capacitor with a capacity range from 0.1 µF to 1µF between VCC5IN pin and GND pin, and between V CC3IN and GND pin, each. * 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.
