General Description
The AOZ1356LI is a current-limiting protection switch
targeting applications that require comprehensive protections.
For AOZ1356LI-01 and -02 the input operating
voltage range is 3.4V to 5.5V, and for AOZ1356LI-
05 and -06, the input operating voltage range is
between 3.6V and 5.3V. 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
internal soft-start circuit controls inrush current due to
highly capacitive loads. The device features very low
quiescent current. The supply current reduces to 6μA
in shut-down. It also has under-voltage lockout
(UVLO), over-voltage protection (OVP) and thermal
shutdown protection.
The AOZ1356LI has True Reverse-Current Blocking
(TRCB) protection to avoid undesired reverse-current
from VOUT to VIN.
The AOZ1356LI supports USB PD Fast Role Swap.
When FON pin is high, the device is in fast turn-on
mode to ensure output voltage rises quickly to meet
USB PD spec. The device also features fast recovery
to turn on power switch once reverse current blocking
protection is de-activated.
The AOZ1356LI is available in 1.31mm x 1.81mm
WLCP package with 0.4mm pitch and 12-bumps.
