CS8191

Precision Air-Core
Tach/Speedo Driver with
Short Circuit Protection

The CS8191 is specifically designed for use with 4 quadrant
air–core meter movements. The IC includes an input comparator for
sensing input frequency such as vehicle speed or engine RPM, a
charge pump for frequency to voltage conversion, a bandgap reference
for stable operation and a function generator with sine and cosine
amplifiers that differentially drive the meter coils.

The CS8191 has a higher torque output and better output signal
symmetry than other competitive parts (CS289, and LM1819). It is
protected against short circuit and overvoltage (60 V) fault conditions.
Enhanced circuitry permits functional operation down to 8.0 V.

Features

CIRCUIT DESCRIPTION and APPLICATION NOTES

The CS8191 is specifically designed for use with air–core
meter movements. It includes an input comparator for
sensing an input signal from an ignition pulse or speed
sensor, a charge pump for frequency to voltage conversion,
a bandgap voltage regulator for stable operation, and a
function generator with sine and cosine amplifiers to
differentially drive the meter coils.

From the partial schematic of Figure 7, the input signal is
applied to the FREQ

lead, this is the input to a high

IN

impedance comparator with a typical positive input
threshold of 2.7 V and typical hysteresis of 0.4 V. The output
of the comparator, SQ

, is applied to the charge pump

OUT

input CP+ through an external capacitor CCP. When the
input signal changes state, CCP is charged or discharged
through R3 and R4. The charge accumulated on C

CP

is
mirrored to C4 by the Norton Amplifier circuit comprising
of Q1, Q2 and Q3. The charge pump output voltage, F /V

OUT

ranges from 2.0 V to 6.3 V depending on the input signal
frequency and the gain of the charge pump according to the
formula:

FV

 2.0 V  2.0  FREQ  CCP RT (V

OUT

REG

 0.7 V)

RT is a potentiometer used to adjust the gain of the F/V
output stage and give the correct meter deflection. The F/V
output voltage is applied to the function generator which
generates the sine and cosine output voltages. The output
voltage of the sine and cosine amplifiers are derived from the

on–chip amplifier and function generator circuitry. The
various trip points for the circuit (i.e., 0°, 90°, 180°, 270°)
are determined by an internal resistor divider and the
bandgap voltage reference. The coils are differentially
driven, allowing bidirectional current flow in the outputs,
thus providing up to 305° range of meter deflection. Driving
the coils differentially offers faster response time, higher
current capability, higher output voltage swings, and
reduced external component count. The key advantage is a
higher torque output for the pointer.

The output angle, Θ, is equal to the F/V gain multiplied by

the function generator gain:
