IDESCRIPTION
The R5532V002 switches between the three VCC voltages (0V/3.3V/5.0V) and the V
PP
voltages (off/0V/3.3V/5.0V).
The R5532V002 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 0.2A(Min.) for VPP.
The R5532V002 is suitable for standard PCMCIA power controllers.

OPERATION
When the VCCOUT =0V is selected, the IC switches into the sleep mode, and draws only nano-amperes of leakage current.
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 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 135
C, the switch transistor turns off. Then, when the temperature of the IC
decreases equal or lower than 125
C, the switch transistor turns on. Unless the abnormal situation of OUT pin is removed or
make them be disable, the switch transistor repeats on and off.
Short over-current level is set internally in the IC. There are three types of response against over-current:
xUnder the condition
that OUT pin is short or large capacity is loaded, if the IC is enabled, the IC becomes constant current state. Current level of
constant current is short current limit.
yWhile 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. After the transient current is beyond the current limit threshold
and current limit circuit responds, the IC becomes into the constant current mode.
zIn the case that load current gradually
increases, the IC is not into the constant current state until the current is beyond over current limit. Once the level is beyond the
over current detector threshold, load current is limited into short current limit level. Note that load current continuously flows
until the load current is beyond the over-current detector threshold.

IAPPLICATION NOTES
* V
CC5IN
voltage should be equal or more than V
CC3IN
.
* 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 V
CC5IN
, some current flows
from OUT to V
CC5IN
