PARAMETER
Compare to V(VDACx)
Note 1
Measure time from V(Voutx) > V(VDACx)
(250mV overdrive) to V(IINx) transition to >
0.9 * V(VCCL).
Measure V(VCCL)-V(ROSC/OVP)
V(Voutx) < [V(VOSEN+) – V(LGND)] / 2
Compare to V(VCCL)
V(Voutx) = 100mV
Compare to V(VCCL)
Compare to V(VCCL)
Compare to V(VCCL)
Compare to V(VDACx)
V(VCCLDRV)=1.8V. Measure V(VCCL)-
V(ROSC/OVP)
Measure time from V(Voutx) > V(VDAC)
(250mV overdrive) to V(ROSC/OVP)
transition to >1V.
1V ≤ V(OCSETx) ≤ 3.3V
