fault detection
? PWM frequency/duty cycle controller
In GPGD Mode the GDx output is a current controlled
output driver with slew rate control, gate to source clamp,
passive pull-down resistor and a drain to gate clamp for
switching inductive loads.
Driver ON /OFF Command
The Driver ON/OFF Command, bits 4 through 7 control
gate drivers that have been Mode Select Command
programmed as GPGD. A logic 1 in bits 4 through 7 will
command the specific output ON. A logic 0 in the appropriate
bit location commands the specific output Off. Also contained
in the Driver ON/OFF Command are SPI control bits for the
integrated LSD output drivers. Further information on LSD
control is provided in the Low Side Injector Driver section of
the data sheet.
END OF SPARK FILTER BITS
The ringing at the end of the Spark signatures waveform
can cause erroneous detection of the End of Spark event. To
eliminate the effect of this ringing, a low pass filter with
variable time values can be selected. Four time values for the
low pass filter have been provided with a zero value
indicating that no low pass filtering is to be used. The End of
Spark Filter bits specify a 0, 4μs, 16μs, or 32μs time interval
to sample the spark ignition coil primary current to ignore the
ringing at the end of spark.
Table 13. End of Spark Filter Time Select
NOTE: Gate drivers programmed to IGNITION mode have
parallel input control only, and cannot be turned off and on via
SPI commands.
GPGD Short Threshold Voltage Command
Each GPGD driver is capable of detecting an open load in
the off state and shorted load in the on state. All faults are
reported through the SPI communication. For open load
detection, a current source is placed between the FBx pin
and ground of the IC. An open load fault is reported when the
FBx voltage is less than the 2.5 V threshold. Open load fault
detect threshold is set internally to 2.5 V and may not be
programmed. A shorted load fault is reported when the FBx

pin voltage is greater than the programmed short threshold
voltage.
The short to battery fault threshold voltage of the external
MOSFET is programmed via the GPGD Short Threshold
Voltage Command. Table 14 illustrates the bit pattern to
select a particular threshold. Drain voltages less than the
selected threshold are considered normal operation. Drain
voltages greater than the selected threshold voltage are
considered faulted.
