General Description

AOZ13984DI-03/04 is enable active low protection switch

intended for applications that require reverse current

protection. The input operating voltage range is from 3.4V

to 22V, and both VIN and VOUT terminals are rated at

28V absolute maximum. The power switch is capable for

15 A surge current for 10ms. AOZ13984DI-03/04 provides

under-voltage lockout, over-voltage, and over-temperature

protection. The FLTB pin flags thermal shutdown, overvoltage, and start up SCP faults.

AOZ13984DI-03/04 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 wide range of output

capacitances on VOUT.

The AOZ13984DI-03/04 is available in a thermally enhanced

3mm x 3mm DFN-12 package which can operate over -40°C

to +125 °C junction temperature range.
