Selection Guide for Protected Power Switch Devices
Step 1. Verify the circuit’s operating parameters.
Confirm that the circuit’s operating parameters are within the following
device ratings.
Input voltage (VIN)
+3 to +5.5V
Output voltage (VOUT)
+3 to +5.5V
Output current per port (IOUT)
0.6A
Operating temperature range
-40 to +85°C
Step 2. Determine the package type and number of switches per
package.
The RYC82xx series are available in a variety of package types and
number of switches per package. Refer to Table P1 for the options
available in package type and switches per package. Dimensions of
each package type are available in Table P3 to confirm the device
selected will fit in your space requirements.
Step 3. Determine the output parameters of the USB controller
chip used in your circuit.
Some USB controller chips have enable logic that requires the power
switch to be active low while others require the switch to be active
high. This signal will be connected to the enable pin of the device
selected. See Table P1 to select the correct enable logic voltage of the
device selected in Step 2 above.
Step 4. Determine your preferred circuit implementation for the
internal Enable (EN) pull-up/pull-down resistors.
The RYC82xx series devices have been designed with an option to
minimize the number of external components to achieve functionality.
Depending on the design of your circuit you may or may not require
the enable resistor to maximize performance of your USB circuit.
Devices with the EN resistor on board may eliminate the need for an
external resistor, thereby reducing external components. See Table
P1 to select the desired configuration for your USB circuit.
Step 5. Independently evaluate and test the suitability of and per-
formance of the selected protected power switch.
