61 / 153 page  Figure 34. Pre-drivers HIZ mode behavior The behavior of the driver depending on the DRV_HIZ and HBn_DIS setting reflects the following truth table: Table 57. Pre-drivers behavior truth table DRV_HIZ HBn_DIS Description 0 0 Pre-driver enabled 0 1 Pre-driver disabled 1 0 Pre-driver in high impedance (Default) 1 1 Pre-driver disabled Note: above described condition in Disable or HIZ conditions are valid for LS drivers as long as VPRE ≥ 2.6 V and for HS as long as VDH ≥ 2.6 V. If these conditions do not hold despite the configuration the drivers are automatically in HIZ mode and the ext. FET Vgs is not driven actively. Table 58.
