AOZ1360
28V Programmable Current-Limited Load Switch
General Description
The AOZ1360 is a member of Alpha and Omega
Semiconductor’s high-side load switch family intended
for applications that require circuit protection. The device
operates from a source voltage between 5.5V and 28V.
The internal current limiting circuit protects the input
supply voltage from large current load. The current limit
can be set with an external resistor. The AOZ1360
provides thermal protection function that limits excessive
power dissipation. The device employs internal soft-start
circuitry to control in-rush current due to highly capacitive
loads associated with hot-plug events. It features low
quiescent current of 220 µA and the supply current
reduces to less than 1 µA at shutdown.
The AOZ1360 is available in either an SO-8 or a
DFN-10 4 mm x 4 mm package which can operate over
a -40C to +85C temperature range.
