Measured at startup from the time when
CLKEN goes low
Measured at FB with

15mV hysteresis (typ)
FB forced 25mV outside the PWRGD trip
thresholds
Measured from the time when FB reaches the
target voltage based on the slew rate set by
R

I
High state, CLKEN, PWRGD, PHASEGD forced
to 5V
Measured at THRM, with respect to V
edge, 115mV hysteresis (typ)
THRM forced 25mV below the VRHOT trip
threshold; falling edge
Low state
High state. VRHOT forced to 5V
Rising edge, 50mV hysteresis, DL_ pulled low
below this level
Falling edge, typical hysteresis = 1.1V, faults
cleared and DL_ forced high when V
below this level
