7.3.2.4 Multi-level inputs (IDRIVE1 and IDRIVE2)

The DRV816x have IDRIVE1 and IDRIVE2 device pins for gate drive current configuration. Each pin can set 8 levels, LEVEL0 to LEVEL7, with an external resistor connected between the device pin and GND. The gate drive current IDRIVEN and IDRIVEP can be determined by Table 7-4. The (G) in the table indicates that VGS monitor dead time insertion is enabled. The IDRIVE1 and IDRIVE2 information are latched at the device power up.
