CS4122
Triple AirCore Gauge
Driver with Serial Input Bus
The CS4122 converts digital data from a microprocessor to
complementary DC outputs and drives aircore meter movements for
vehicle instrument panels. It is optimized for one 360
°
gauge and two
112
°
gauges. The digital data controls the voltage applied to the
quadrature coils of the meters with a 0.35
°
resolution for the major
(360
°
) gauge and 0.44
°
resolution for the minor (112
°
) gauges. The
accuracy is
±
0.75
°
for the major and
±
1.00
°
for the minors. The
interface from the microcontroller is by a SPI compatible serial
connection using up to a 2.0 MHz shift clock rate.
The digital code is shifted into the appropriate DAC and
multiplexer. These two blocks provide a tangential conversion
function to change the digital data into the appropriate DC coil
voltage. The major gauge driver can position a pointer anywhere
within a 360
°
circle while the minor gauge drivers are limited to an arc
of 112.2
°
.
The output buffers are capable of 70 mA per coil and are protected
against output short circuit conditions. A thermal protection circuit
limits the junction temperature to approximately 160
°
C.
An opendrain fault output goes low when any of the outputs are
shorted or the device is in a thermal shutdown state. This ASIC is
designed on POWERSENSE
3.0.
