General Description

AOZ1358LI-01 is a current-limiting protection switch for

USB Type-C PD current-sourcing applications. The input

operating voltage range is from 3.8V to 5.5V and the

VOUT terminal is rated at 29V absolute maximum to

protect the device when used in high voltage PD

applications. There is an internal current-limiting circuit to

protect the supply from large load currents. The current

limit threshold is set with an external resistor. The device

also has an internal soft-start circuit to control inrush

current due to highly capacitive loads.

AOZ1358LI-01 supports USB PD Fast Role Swap (FRS).

When FON pin is high, the device is in fast-turn-on mode

to ensure output voltage rises quickly to meet the USB

PD specification.

AOZ1358LI-01 features Ideal Diode Reverse-Current

Blocking (IDRCB) protection to prevent reverse current

flow from VOUT to VIN at any load. This feature complies

with the USB PD specification. The device also features

fast recovery from reverse blocking to prevent excessive

VOUT droop in power swap applications

The device offers other protection features including

surge protection, Under-Voltage LockOut (UVLO), Short

Circuit Protection (SCP) and Thermal Shut Down (TSD).

AOZ1358LI-01 is available in 2.01mm x 2.05mm WLCSP

package with 0.5mm pitch and 16 bumps.
