General Description

The AOZ13929DI-01 is a protection switch intended for

applications that require reverse current protection. The

input operating voltage range is between 3.4 V and 23 V, and

both VIN and VOUT terminals are rated at 28 V Absolute

Maximum. The power switch is capable for 20 A surge

current for 10 ms. AOZ13929DI-01 provides under-voltage

lockout, startup short circuit protection, over-voltage and

over-temperature protection. AOZ13929DI-01 also has

integrated TVS diode for surge protection.

AOZ13929DI-01 is the ideal solution for multi-port Type-C 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 a wide range of output

capacitances on VOUT.

The AOZ13929DI-01 is available in a thermally enhanced

3.2 mm x 5.5 mm DFN-17L package which can operate over

-40°C to +125°C junction temperature range.
