# Half-Bridge Mode

In Half-Bridge mode, two output signals are generated as true and inverted versions of the input as illustrated in Figure 1. A non-overlap (dead-band) time is inserted between the two outputs to prevent shoot-through current in various power supply applications. Dead-band control is described in Dead-Band Control. The output steering feature cannot be used in this mode. A basic block diagram of this mode is shown in Figure 2.

The unused outputs CWGxC and CWGxD drive similar signals, with polarity independently controlled by the POLC and POLD bits, respectively.
