MAXI DAC BITS
The MAXI control block provides a means to shut off all the
ignition coil drivers if the current reaches a SPI
programmable maximum level. Control is achieved by
comparing the output of the current sense amplifier with a SPI
programmed DAC value.
The MAXI comparator disables all gate drivers configured
as ignition drivers when the DAC MAXI setting is exceeded.
When a MAXI event occurs, the MAXI bit in the fault status
register is set and the MAXI pin is asserted (High).
When using a 20 m Ω resistor as the current sense resistor,
the gain select of the differential amplifier connected to RSP
and RSN, should be set to a gain of 2, via the SPI Command
Message Spark Command (Command 0100, hex 4), Control
bit 6 =1.
When using a 40 m Ω resistor as the current sense resistor,
the gain select of the differential amplifier connected to RSP
and RSN, should be set to a gain of 1, via the SPI Command
Message Spark Command (Command 0100, hex 4), Control
bit 6 =0. This is also the default value.
The MAXI fault bit in the SPI fault status register is cleared
when the MAXI condition no longer exists and the SPI fault
status register has been read by the MCU.
In V10 Mode, the MAXI pin is configured as an input to
receive the MAXI signal from a second MC33810 device in
the system. In this mode a input MAXI signal has effectively
the same control as an internal MAXI signal. Further
information is provided in the V10 Mode application section
of this specification.
