Power bridges

Figure 17. Half bridge configuration
In this case each half bridge will behave according to the following truth table.
Table 19.
When “low power mode” bit is active the bridges will reduce its biasing thus contributing to
the power saving.
When a current limit event occurs this event will be latched and the bridges will remain in
high impedance state for the off time.
