ELECTRICAL CHARACTERISTICS
TIMING DIAGRAMS
• During tochx, the device can reach up to Ioch0 over-
current level.
• During tocl3 or tocl2 or tocl1 or tocl0, the device can be
programmed to detect up to Iocl0.
Figure 6 illustrates the over-current detection level (Ioclx,
Iochx) the device can reach for each over-current detection
blanking time (tochx, toclx):
