Definition
The Output Enable pin (OUTEN) is an active low input. When the OUTEN
pin is low, the device outputs are active. The outputs are disabled when
OUTEN is high.

Output Enable
This pin is the Maximum Ignition Coil Current output flag. This output is
asserted when the IGBT Collector-Emitter current exceeds the selected
level of the DAC. This signal also latches off the gate pre-drive outputs
when configured as a General Purpose Gate pre-Driver. The MAXI
current level is determined by the voltage drop across an external sense
resistor connected to pins RSP and RSN.

This pin is the Nominal Ignition Coil Current output flag. This output is
asserted when the IGBT Collector-Emitter current exceeds the level
selected by the DAC.

In IGBT ignition gate pre-driver mode, these feedback inputs monitor the
IGBT's collector voltage to provide the spark duration timer control signal.

Sense
IGBT/General Purpose Gate pre-driver outputs are controlled by GIN0 -
GIN3. Pull-up and pull-down current sources are used to provide a
controlled slew rate to an external IGBT or MOSFET connected as a low
side driver.
