events while using only two current sense resistors. This is
achieved using three MC33810 devices. Two MC33810
devices are programmed as Normal Ignition mode outputs
and one is programmed as a V10 ignition mode output. The
ignition gate driver outputs are partitioned into two banks of
five outputs each (See Figure 10 ). Each bank contains one or
two driver(s) from the V10 device.
Drivers in the V10 device are grouped in two’s (GD0&GD2,
GD1&GD3). Current from each V10 mode IGBT group is
monitored by the appropriate Normal Mode device (See
ported to the V10 Mode MAXI input pin. Likewise the MAXI
signal from the second Normal Mode device is ported to the
V10 Mode NOMI input pin. The V10 Mode NOMI/MAXI inputs
are used as MAXI shutdown signals for the appropriate
ignition gate drive group.
Notes: Tolerance on selected frequency is ±10% after using the
Calibration Command. Shorts to battery and open load faults will not
be detected for frequency and duty cycle combinations inconsistent
with fault timers.
Table 17. Pre-driver GDx Output Control
V10 Mode contains the same features as Ignition Mode
gate drivers with the following exceptions:
? NOMI/MAXI configured as input pins
? MAXI shutdown for GPGD disabled
? NOMI/MAXI comparators disabled
