General Description
AOZ13987DI-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 20A surge
current for 10ms. AOZ13987DI-02 provides undervoltage
lockout, over-voltage, and over-temperature
protection. The FLTB pin flags thermal shutdown and
over-voltage faults.
AOZ13987DI-02 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 AOZ13987DI-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.
