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 pin signals in each phase are high at the same time, both the high- and low-side

transistors become on (simultaneous on-state). Therefore, HINx and LINx signals, the input signals for the HINx and

LINx pins, require dead time setting so that such a simultaneous on-state event can be avoided.

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).
