Compare Duty Cycle to GATEHX
Below Internal Ramp1 Start Voltage
VCCLX= 8V. Step EAOUT from .8V to
.3V and measure time to GATELX
transition to < 7V.
Compare to V(VREF)
VCC=OVPSNS where V(OVP)>0.5V.
Same for 5VUVL=OVPSNS.
VCC=2V, V(OVP) >0.5V. Same for
V(5VUVL)=2V.
VCC=12V, V(OVPSNS)=1V,
VREF=1.6V, where OVP<0.5V
VCCLX= 8V. V(EAOUT)=0V. Step
OVPSNS 540mV + V(VREF). Measure
time to GATELX transition to >1V.
Note 1.
V(OVP)=0.5V, VCC=1.8V, 5VUVL=0V
OVP to LGND
I(OVP)=10uA, V(VCC) or V(5VUVL)-
V(OVP), VCC=1.8V
I(5VREF)=0A
V(VCC)=16V
-0.3V
V(VCCHX)=28V, V(VCCL3)=14V
V(VCCL1_2)=14V
V(5VUVL)=5V, no OVP condition
