General Description

AOZ13986DI-02 is protection switch intended for

applications that require reverse current protection. The

input operating voltage range is from 3.4V to 23V, and

both VIN and VOUT terminals are rated at 28V absolute

maximum. The power switch is capable for 18A surge

current for 10ms. AOZ13986DI-02 provides undervoltage lockout, over-voltage, and over-temperature

protection. The FLTB pin flags thermal shutdown and

over-voltage faults.

AOZ13986DI-02 is the ideal solution for multi-port TypeC PD current sinking application. The Ideal Diode True

Reverse Current Blocking (IDTRCB) feature prevents

VIN to rise due to reverse current flow from VOUT under

all conditions.

An internal soft-start circuit controls inrush current due to

highly capacitive loads and the slew rate can be adjusted

using an external capacitor. The integrated back-to-back

MOSFET offer industry’s lowest ON resistance and

highest SOA to safely handle high current and wide

range of output capacitances on VOUT.

The AOZ13986DI-02 is available in a thermally

enhanced 3mm x 3mm DFN-12 package which can

operate over -40°C to +125 °C junction temperature

range.
