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 5.
In independent half-bridge control mode, current sensing and feedback are still available, but the internal current regulation is disabled since each half-bridge is operating independently. Additionally, if both low-side MOSFETs are conducting current at the same time, the IPROPI scaled output will be the sum of the currents. See Current Sense and Regulation for more information.
