AOZ1331ADI
Dual Channel Smart Load Switch
General Description
The AOZ1331ADI is a dual channel load switch with typ-
ical 20mon-resistance in a small package. It contains two
n-channel MOSFETs for up to 5.5V input voltage opera-
tion and 6A current each channel with 2.5V to 5V bias
supply. Each load switch is independently controlled by a
low voltage control signal through ON1/ON2 pin.
The AOZ1331ADI integrates an internal 250load resis-
tor in each channel for quick output discharge when load
switch is off. The optional external capacitor connected
CT1/CT2 for output slew rate control.
The AOZ1331ADI is available in a 3mm x 2mm DFN-14L
package with bottom thermal pad and is rated over a
-40°C to +85°C ambient temperature range.

Pin Function
Switch 1 Input. Bypass capacitor is recommended to minimize input voltage dip.
Enable Input of Switch 1. Switch 1 is on when ON1 is pulled high, and is off when ON1 is
pulled low. Do not leave floating.
Bias Voltage. Power supply to this device. Recommended voltage range is 2.5V to 5.5V.
Enable Input of Switch 2. Switch 2 is on when ON2 is pulled high, and is off when ON2 is
pulled low. Do not leave floating.
Switch 2 Input. Bypass capacitor is recommended to minimize input voltage dip.
Switch 2 Output.
Slew rate control of switch 2.
