4.3.3 Driver Control Page (HW Device Variant)

There are a few other minor differences between the SPI and HW device variant which are noted below:

  • WAKE For the Hardware variant, selecting the jumpers while the device is asleep is necessary, and the default for the HW variant is "=asleep. If the user makes changes to the jumpers while the device is awake, then the device does not recognize those changes.
  • ENABLE DRIVER Directly controls the DRVOFF pin. When the bridge control is active the user cannot observe the passive diagnostics.
  • MODE In Hardware variant, mode change must occur through jumpers while the GUI WAKE control is Asleep. See Figure 2-8. Level 1 is PH/EN Mode, Level 2 is Independent Half-Bridge Mode, and Level 4 is PWM mode, as can be observed in the device data sheet. For Level 4, there is no jumper. The jumper settings for these Mode changes can be observed in Section 2.4. For Independent Half-Bridge Mode, the user must correctly connect for either High-Side Load or Low-Side Load as can be observed in Figure 4-6.
  • PASSIVE/ACTIVE DIAGNOSTICS The active diagnostics controls do not exist on hardware devices. Only the passive diagnostics can be observed.

    CAUTION:

    Driving an incorrectly connected load can result in permanent damage to the device, fire, or other damage.

    When operating the EVM at the maximum device specifications and higher ambient temperature, external cooling fans can be required to minimize potential fire hazard, personal injury, or both.
