CS8190

Precision Air-Core

Tach/Speedo Driver with

Return to Zero

The CS8190 is specifically designed for use with air–core meter

movements. The IC provides all the functions necessary for an analog

tachometer or speedometer. The CS8190 takes a speed sensor input

and generates sine and cosine related output signals to differentially

drive an air–core meter.

http://onsemi.com

Many enhancements have been added over industry standard

tachometer drivers such as the CS289 or LM1819. The output utilizes

differential drivers which eliminates the need for a zener reference

and offers more torque. The device withstands 60 V transients which

decreases the protection circuitry required. The device is also more

precise than existing devices allowing for fewer trims and for use in a

speedometer.

CIRCUIT DESCRIPTION and APPLICATION NOTES

The CS8190 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.

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.

From the partial schematic of Figure 7, the input signal is

applied to the FREQ lead, this is the input to a high

CC

increases the time between these undervoltage points since

the capacitor discharges slowly and ensures that the needle

moves towards 0° as opposed to 360°. The exact value of the

capacitor depends on the response time of the system,the

maximum meter deflection and the current consumption of

the circuit. It should be selected by breadboarding the design

in the lab.

The CS8190 has an undervoltage detect circuit that disables

the input comparator when V falls below 8.0 V(typical).

With no input signal the F/V output voltage decreases and the

needle moves towards zero. A second undervoltage detect

Notes:

1. C2 = 10 µF with CS8441 application.

2. The product of C4 and R have a direct effect on gain and therefore directly affect temperature compensation.

3. C4 Range; 20 pF to 0.2 µF.

4. R4 Range; 100 kΩ to 500 kΩ.

5. The IC must be protected from transients above 60 V and reverse battery conditions.

6. Additional filtering on the FREQ lead may be required.

IN

7. Gauge coil connections to the IC must be kept as short as possible (≤ 3.0 inch) for best pointer stability.
