AOZ1331ADI
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.

Features AOZ1331ADI Dual Channel Smart Load Switc h General Description The AOZ1331ADI i s a dual channel load switch with typic al 20mΩ on-resistance in a small pack age. It contains two n-channel MOSFETs for up to 5.5V input voltage operation and 6A current each channel with 2.5V t o 5V bias supply. Each load switch is i ndependently controlled by a low voltag e control signal through ON1/ON2 pin. T he AOZ1331ADI integrates an internal 25 0Ω load resistor in each channel for quick output discharge when load switch is off. The optional external capacito r connected CT1/CT2 for output slew rat e control. The AOZ1331ADI is available in a 3mm x 2mm DFN-14L package with bot tom thermal pad and is rated over a -40 °C to +85°C ambient temperature range . Features  0.8V to 5.5V input volt age range  6A continuous current per channel  Low RDS(ON) internal NFETs – 20mΩ at VBIAS = 5V  Low quies cent current – 80µA (both channels) – 60µA (single channel)  Adjustable rise time  2.5V to 5V bias voltage  Integrate.
