5.3 Independent Half-Bridge Control Mode (PMODE = Hi-Z)
When the PMODE pin is Hi-Z on power up, the device is latched into independent half-bridge control
mode. This mode allows for each half-bridge to be directly controlled in order to support high-side slow
decay or driving two independent loads. The truth table for independent half-bridge mode is shown in
Table 3 .
