the load. All outputs may be configured individually as
desired. When Low-Side Drive is used, the 33880 limits the
positive transient for inductive loads to 45 V.
SOURCE OUTPUT (S1 – S8)
High-Side Drive configurations, the source pins are
connected directly to the load. In Low-Side Drive
configurations the source is connected to ground. All outputs
may be configured individually as desired. When High-Side
drive is used, the 33880 will limit the negative transient for
inductive loads to -20 V.
The S1 – S8 pins are the source outputs of the 33880. For
