dissipation over a longer period of time, thus allowing the use
of a lower energy rated IGBTs. The internal low-voltage
clamp is connected between the IGBT's collector (through an
external resistor) and the IGBT's gate. The energy stored in
the ignition coil is dissipated by the IGBT, not the internal
clamp. The internal clamp only provides the bias to the IGBT.
Several logical signals are required as inputs to activate
the GDx Low-voltage Clamp feature. The GDx Low-voltage
Clamp feature may be disabled through bit 4 of the Spark
Command message.

The Low-voltage Clamp is an internal clamp circuit which
biases the IGBT's gate voltage in order to control the collector
to emitter voltage to VPWR+11V. This technique is used to
dissipate the energy stored in the ignition coil over a longer
period of time than if the internal IGBT clamp were used.
In the open secondary fault condition, all of the stored
energy in the ignition coil is dissipated by the IGBT. This fault
condition requires the use of a higher energy rated IGBT than
would otherwise be needed.
SOFT SHUTDOWN ENABLE
The soft shutdown feature is enabled via the SPI by
asserting control bit 5 in the Spark Command message.
When enabled, the following events initiate a soft
shutdown control of the gate driver.
