Figure 8-18 shows the ground connected load with internal OLD circuit. When high-side open load sequence is activated (i.e. SW1_HS is on and SW1_LS is off), the current source (IOL_PU) pulls up the OUT1 node to internal regulator voltage (AVDD) and current flows from internal regulator voltage (AVDD) to ground via the connected load (RL). Now, depending upon if the load is present or not, there can be three cases as follows:
