AOZ1361DI
28V Programmable Current-Limited Load Switch
General Description
The AOZ1361DI is a high-side load switch intended for
applications that require circuit protection. The device
operates from voltages between 4.5V and 28V. The
internal current limiting circuit protects the input supply
voltage from large load current. The current limit can be
set with an external resistor. The AOZ1361DI provides
thermal protection function that limits excessive power
dissipation. The device employs internal soft-start
circuitry to control inrush current due to highly capacitive
loads associated with hot-plug events. It features low
quiescent current of 220µA and the supply current
reduces to less than 1µA in shutdown.
The AOZ1361DI is available in a 10-pin 4x4 DFN
package and can operate over -40°C to +85°C
temperature range.
