General Description
The AOZ1353DI is a current-limited load switch targeting
applications that require comprehensive protections. The
input operating voltage range is between 3.4V and 5.5V.
The output terminal is rated 28V absolute maximum. The
internal current-limiting circuit protects the supply from large
load current. The current limit level is set with an external
resistor. The soft-start circuit controls inrush current due to
highly capacitive loads. The soft-start time can be optionally
adjusted with an external capacitor. The device features very
low quiescent current of 80μA. The supply current reduces
to less than 1μA in shut- down. It also has under-voltage
lockout (UVLO), over- voltage protection (OVP) and thermal
shutdown protection.
The AOZ1353DI has True Reverse-Current Blocking (TRCB)
protection to avoid undesired reverse-current from VOUT to
VIN.
The device features fast recovery to turn on power switch
once reverse current blocking protection is de-activated.
The AOZ1353DI is available in 3mm x 3mm DFN-12L
package.
