ELECTRICAL CHARACTERISTICS
TIMING DIAGRAMS
Figure 6 illustrates the over-current detection level (I_OCLX,
I_OCHX) the device can reach for each over-current detection
blanking time (t_OCHX, t_OCLX):
• During t_OCHX, the device can reach up to I_OCH0 over-
current level.
• During t_OCL3 or t_OCL2 or t_OCL1 or t_OCL0, the device can be
programmed to detect up to I_OCL0.
