This pin is the gauge power control pin for the external pass device.
Refer to
This pin is the regulated gauge voltage input. Refer to
Sequencer and
Two pins are provided for a separate gauge driver ground, V
as the current return only for the coil driver circuitry, it is a high-current
pin.
This pin is the feedback pin for the gauge power regulator. External
resistors as shown in
the MC68HC705V12
V
These pins are the full H-bridge coil driver pins. The A or B refer to pins
associated with major gauge A or gauge B, and pin 1+/ or pin 2+/ refer
to coil 1 or coil 2 of that major gauge and the direction of current flow.
Refer to
operation of these pins.
MINA(B,C,D)2+ and MINA(B,C,D)2 are the full H-bridge driver pins
used with or for the minor gauges. These pins allow the coil current to be
reversed for movement of gauge pointer from 0 to 180 degrees.
