TEST CONDITION

RROSC = 42kŸ

GATEH1 rise to GATEH2 rise

RROSC = 42kŸ

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),

CSIN=CSINP1=CSINP2, Note 1.

RROSC = 42kŸ
