Figure 5. Overcurrent Shutdown

Figure 6. Overcurrent Low and High Detection

Figure 6 illustrates the overcurrent detection level (IOCLX, IOCHX) the device can reach for each overcurrent detection blanking time (tOCHX,

tOCLX):

• During tOCHX, the device can reach up to Ioch0 overcurrent level.

• During tOCL3 or tOCL2 or tOCL1 or tOCL0, the device can be programmed to detect up to Iocl0.
