PRELIMINARY INFORMATION - AUG 01, 2011
5.6.2
1) not tested during production test, guaranteed by design.
5.7
The high side driver block and the low side driver block are physically separated.
The driver control is managed by two driver control modules. One governs all the high side drivers and
one all the low side drivers.
5.7.1
The HSD control can be separated into two different modes:
•
•
The principle of the HSD control module is shown in pictures Fig. 11 below.
