tPP_5V_ovp

Response time to VVBUS > VOVP4RCP

Enable PP_5V, IRpDef

being drawn from PP5V,

configure VOVP4RCP to

setting 2, ramp VVBUS from

4V to 20V at 100V/ms,

CPP5V = 2.5 µF, measure

time from OVP detection

until reverse current <

100mA

VPP5V = 5.5V, IRpDef

being drawn from PP5V,

enable PP_5V, configure

VOVP4RCP to setting 2,

ramp VVBUS from 4V to

21.5V at 10 V/µs, measure

VPP5V. CPP5V = 104µF,

CVBUS=10µF, measure time

from RCP detection until
