TEST CONDITION

RROSC = 47kŸ

Sequence: GATEH1-GATEH2-GATEH3

RROSC = 47kŸ

V(SETBIAS)-V(BIASOUT) @ 100mA

I(BIASOUT)=100mA,Threshold when

V(SETBIAS)-V(BIASOUT)=0.45V

With FB = 0V, adjust V(SS/DEL) until

EAOUT drives high

Relative to Charge Voltage

V(OCSET)-V(VDAC),

CSINM=CSINP1=CSINP2=CSINP3,

Note 1.
