AOZ1363DI
16V High Current Load Switch with Rapid Turn-Off
and Current Monitoring Protection
General Description
The AOZ1363DI is a high-side load switch intended for
applications that require circuit protection. The device
operates from voltages between 5V and 16V, and
capable of supplying 6A of continuous current. The
internal current limiting circuit protects the input supply
voltage from large load current. The AOZ1363DI
provides thermal protection function that limits excessive
power dissipation. The device employs an externally
programmable soft-start circuitry to control inrush current
due to highly capacitive loads associated with hot-plug
events. It features low quiescent current of 400µA and
the supply current reduces to less than 10µA in
shutdown.
The device can output current monitoring information
with an accuracy of 10% at a specified load current of 3A.
The device can detect the over-current fault condition
and execute the switch power down within a maximum
delay time of 100ns. It features an input overvoltage
protection where the device powers down when the
power input voltage exceeds 19V.
The AOZ1363DI is available in a 3mm x 3mm DFN-12L
package and can operate over -40 C to +85 C
temperature range.

Pin Function
Enable Input. Active high. For automatic enabling, this pin is highly recommended to
connect to VCC.
VCC is a bypass pin. Connect a 0.47nF capacitor from VCC to GND.
Ground.
Fault Output pin. This is an open drain output that is externally pulled high with a
pull-up resistor. Drain is internally pulled down to GND to indicate a fault condition.
Connect to 5V, 3.3V, or VCC through a 100kpull-up resistor.
N-channel MOSFET Drain. Connect a 100µF capacitor from IN to GND
No Connection.
Externally Programmable Soft-Start pin.
Current Sense Information Output. See Figure 3 for Rsen value.
N-channel MOSFET Source. Connect a 4.7µF capacitor from OUT to GND.
