The OCL feature is enabled when the OCL and SD pins are tied together externally. If these pins are not tied when an OCL

condition occurs, device operation continues in Normal mode.

Returning to the Normal mode of operation from a VCC UVLO condition, a high-side MOSFET resumes switching

on the rising edge of an HINx input. On the other hand, a low-side MOSFET resumes switching on the first logic high

of a LINx input after release of the UVLO condition.

Returning to the Normal mode of operation from a VB UVLO condition, a high-side MOSFET resumes switching on the rising

edge of an HINx input.

Note: To prevent a shoot-through condition, the external microcontroller should not drive HINx = LINx = H at the same time.
