Truth Table
Table 6-1 is a truth table that provides the logic level definitions of operation modes.
In the case where HINx and LINx signals in each phase are high at the same time, the simultaneous on-state
prevention sets both the high- and low-side transistors off.
After the IC recovers from a UVLO_VCC condition, the high- and low-side transistors resume switching, according
to the input logic levels of the HINx and LINx signals (level-triggered).
After the IC recovers from a UVLO_VB condition, the high-side transistors resume switching at the next rising edge
of an HINx signal (edge-triggered).
