Single Air−Core Gauge
Driver
translate a digital 10−bit word from a microprocessor/microcontroller
to complementary DC outputs. The DC outputs drive an air−core
meter commonly used in vehicle instrument panels. The 10 bits of data
are used to linearly control the quadrature coils of the meter directly
with a 0.35 resolution and 1.2 accuracy over the full 360 range of
the gauge. The interface from the microcontroller is by a Serial
Peripheral Interface (SPI) compatible serial connection using up to a
2.0 MHz shift clock rate.
pointer deflection, is shifted into a DAC and multiplexer. These two
blocks provide a tangential conversion function to change the digital
data into the appropriate DC coil voltage for the angle demanded. The
tangential algorithm creates approximately 40% more torque in the
meter movement than does a sin−cos algorithm at 45 , 135 , 225 , and
315 angles. This increased torque reduces the error due to pointer
droop at these critical angles.
the buffers are controlled by a common OE enable pin. The output
buffers are turned off when OE is brought low, while the logic portion
of the chip remains powered and continues to operate normally. OE
must be high before the falling edge of CS to enable the output buffers.
The status pin (ST) reflects the state of the outputs and is low
whenever the outputs are disabled.
Each driver is protected for 125 mA (typ) overcurrent while a global
thermal protection circuit limits junction temperature to 170 C (typ).
The output drivers are disabled anytime the IC protection circuitry
detects an overcurrent or overtemperature fault. The drivers remain
disabled until a falling edge is presented on CS. If the fault is still
present, the output drivers automatically disable themselves again.
