14.1.1 Full
bridge
When in full bridge configuration, the drivers will behave according to the following truth
table:
table:
Note:
Note: When “low power mode” is active, the bridges will enter in low power state and will
reduce its biasing thus contributing to the power saving.
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.
