Power bridges
SABRE-LL-I
52/141
The possible configurations for the bridges are described in the following:
14.3.1
Full bridge
When in full bridge configuration, the drivers will behave according to the following truth
table:
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.
When a current limit event occurs this event will be latched and the bridges will remain in high
impedance state for the toff time.
