L6599AT gate drive pulses appear unexpectedly

We noticed that there are pulses at the gate drive outputs (pins 15 HVG, & 11 LVG) during the ramp-up of the control voltage (pin 12 VCC).This is what we saw: when VCC reaches about 11V, a sequence of pulses appear on both LVG and HVG. First LVG went...

L6599AT Questions Q1: STBY pin does not stop pulses on gate drive outputs. Q2: Datasheet confusion for: (a) Soft-Start, (b) LINE.

Question 1:In our circuit Pin 5 STBY is pulled down to 0V to instantly stop pulses on gate drives. But sometimes when STBY=0V we still see pulses at the gate driver outputs LVG, HVG. The datasheet does not mention that gate pulses may still happen.I ...
