General Description
The AOZ1356DI is a current-limiting protection switch
targeting applications that require comprehensive
protections. For AOZ1356DI-01 and -02 the input
operating voltage range is 3.4V to 5.5V, and for
AOZ1356DI-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 currentlimiting
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 AOZ1356DI has True Reverse-Current Blocking
(TRCB) protection to avoid undesired reverse-current
from VOUT to VIN.
The AOZ1356DI 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 AOZ1356DI is available in 3mm x 3mm 12-Pin DFN
package.
