The complementary low-side drivers can be used in conjunction with an external PMOS FET to provide single-ended direct excitation to the transducer. In this configuration, the internal FETs can be used in a RDSON mode by disabling current limiting feature by setting the DIS_CL bit in the CURR_LIM_P1 register.
An additional dead-time feature can be used in this mode to eliminate the shoot-through currents between the external PMOS FET and internal low-side FETs by configuring the PULSE_DT bit. The burst cycle period of the low-side FETs remains unchanged; however, the deactivation time is reduced by the dead-time programmed value. Figure 4 shows this case.
