PARAMETER
Note 1
VCCH = 12V. Measure time from
RMPIN input (50mV overdrive) to
GATEL transition to <11V.
Clamp and Current Share Adjust OFF
VCCH = 12V. Measure time from
PWMRMP input (50mV overdrive) to
GATEH transition to < 11V.
Exceeding the Common Mode input
range results in 100% duty cycle
EAIN – PWMRMP, Note 1
Note 1
Amount SCOMP must increase from its
minimum voltage until the Ramp Slope
Adjust current equals = 10µA
I(PWMRMP) = 500µA
Compare to V(DACIN)
VCCL = 12V. Measure time from EAIN
< 0.9 x V(DACIN) (200mV overdrive) to
GATEL transition to < 11V. Note 1.
Compare to V(DACIN)
I(PHSFLT) = 4mA
V(PHSFLT) = 5.5V
I(VRHOT) = 29mA
V(VRHOT) = 5.5V
