Figure 5-6. DRV814x High Side and Low Side Connections
In the DRV824x devices, Phase/Enable mode only has one duty cycle slider while the Independent Half-
bridge mode and PWM mode each have two sliders.
When changing between modes, there will be a "Load Connection Warning" popup. If the load is incorrectly
connected and the user attempts to run the motor on the GUI it can damage the device and may cause harm
to the user. This is especially important when in Independent Half-Bridge mode. The load connection warning
will appear every time the user selects a new mode or repeatedly selects the current mode.
Figure 5-7 shows
the pop-up window for the Independent Half-Brige mode selection.
Note
With the DRV824x devices, the GUI allows to switch between high side and low side load
connection only using the Independent Half-Bridge mode selection pop-up window.
