This parameter is measured with RT = 10 k to VREF. This contributes approximately 300 A of current to the measurement. The total
current flowing into the RT/CT pin will be approximately 300 A higher than the measured value.
(3)
Parameters ensured by design and/or characterization, if not production tested.
(4)
Parameter measured at trip point of latch with VFB = 0 V.
(5)
Gain defined as: G =
ΔVComp/ΔVISENSE; VISENSE = 0 to 0.8 V.
