• Adjustable angle range

• Adjustable zero point.

GENERAL DESCRIPTION

The UZZ9000 is an integrated circuit that combines two
sinusoidal signals (sine and cosine) into one single linear
output signal. When used in conjunction with the
magnetoresistive sensor KMZ41 it provides a
measurement systemfor angles up to 180°. The UZZ9000
can also be used for other applications in which an angle
has to be calculated from a sine and a cosine signal.
A typical application would be any kind of resolver
application.
The two input signalsare convertedinto thedigital domain
with two separate AD-converters. A CORDIC algorithm
performsthe inverse tangenttransformation.Sincetoday’s
applications typically require analog output signals
(e.g. potentiometers), the resulting signal is transferred
back to the analog domain.
TheUZZ9000 enablesthe userto setboth the anglerange
and the zero point offset. Theseranges areset byexternal
voltage dividers.

FUNCTIONAL DESCRIPTION

The UZZ9000is a mixedsignal IC for angle measurement
systems. The UZZ9000 has been designed for the double
sensor KMZ41. It combines two analog signals (sine and
cosine) into a linear output signal. The analog
measurement signals on the IC input are converted to
digital data by two ADC’s. Each ADC is a Sigma-Delta
modulator employing a 4th order continuous time
architecture with an over-sampling ratio of 128 to achieve
high resolution. The converteroutput isa digitalbit-stream
with an over-sampling frequency of typically 500 kHz.
The bit-stream is fed into a decimation filter which

2000 Nov 27 4

performs both low pass filtering and down-sampling. The
IC has twoinput channels each of which has its own ADC
and decimationfilter. The twodecimation filter outputsare
15-bit digital words at a lower frequency of typically

3.9 kHz which is the typical sampling frequency of the
sensor system. The digital representations of the two
signals arethen used to calculatethe current angleby the
ALU. This calculation is carried out using the so-called
CORDIC algorithm. The angle is represented by a 13-bit
resolution. A DAC converts the digital signal back to the
analog domain.

The following list gives a short description of the relevant
block functions:

1. The ADC block contains two Sigma Delta AD
converters, sensor offset correction circuitry and the
circuitry required for the sensitivity and offset
adjustment of the chip output voltage curve.

2. The decimation filter block comprises two digital low
pass decimation filtersconvert the low resolution high
speed bit stream output from the ADC’s into a low
speed digital word.

3. The ALU block derives an angle value from the two
digital inputs using the CORDIC algorithm.

4. The DAC converts the output of the ALU block to an
analog signal.

5. The CONTROL block provides the clock and the
control signals for the chip.

6. The RESET block supplies a reset signal during
power-up and power-down when the power supply is
below a certain value.

7. The Oscillator generates the master clock.

Angle range selection

In order to accommodate varying applications, both the
mechanical input angular range of the UZZ9000 and the
zeropoint oftheoutput curveareuser programmable.This
section describes how to select a desired mode.
The output curve is adjusted by changing the angular
range asshown inFig.2. Without anyzero pointoffset, the
ramp-up starts at mechanical 0° (α1=0°). When using a
KMZ41 sensor, the maximum angular range ∆α
is 0° to 180°. For the UZZ9000, smaller angular ranges
can be set. In this case, α2 becomes smaller than 180°
and the output curve is clipped at this position. The
location of discontinuity XD (change from lower to upper
clipping area) depends on the adjusted range and can be
calculated as follows:

Inorder tocompensate fortolerances, thezero point ofthe
output curve can be shifted by ±5˚ in steps of 0.5°. The
effect of this measure is shown in Fig.3. Now α1 is no
longer identicalwith mechanical 0˚,but with the zero point

Angle range setting

To select one of 16 different angular ranges, an external
voltage (see Table 1) must be applied to pin 13 of the
UZZ9000 (Var). During the ICs initialisation phase, which
directly follows power-on reset or an external reset, this
voltage isread and thenconverted into the digital domain.
The digitalvalue is stored until thenext reset stateoccurs.
Consequently, the angular range cannot be changed
during normal operation but is still fixed after initialisation
phase. Note that thevoltage at pin 13 must be ratiometric
toV

andalso stableover temperatureand lifetime. This

DDA

is ensured, for instance, when providingthis voltage via a
(trimmable) resistor divider connected to V

DDA

, which is
the analog supply of the UZZ9000. The following defines
the % value of the supply voltage V

that must be

DDA

supplied to pin 13 to select a certain range. When using
the 30° angular range, a constant zero point offset of 15°
is added. Consequently, when using the 30° range, the
zeropoint offsetcan beprogrammed between10° and20°
only (see Zero point offset setting).

Zero point offset setting

To adjustthe zeropoint offset orto set it to 0°,an external
voltage has to be applied to the UZZ9000 at pin 14
(VOFFIN). The function is similar to that described

previously. After reset the voltage is read, converted into
the digital domain andthen storeduntil anotherreset state
occurs. Consequently, the zero point offset cannot be
adjusted without a reset. It is recommended to use a
resistordivider connectedtoV

togenerate thisvoltage.

Offset trimming

To achievea linear outputcharacteristic, it is necessary to
adapt theoffsets of the two inputsignals to theinput stage
of the UZZ9000. For this reason a sensor offset
cancellation procedure has been implemented in the
UZZ9000 whichis started by sendinga special serial data
protocol to the UZZ9000. This trimming procedure is
required for both input signals.

Trim interface

The serial interface used to switch the UZZ9000 into trim
mode consists of the two terminals SMODE (pin 10) and
DATA_CLK (pin 9).The structureof this protocolis shown
in Fig.4.
All signal levels at DATA_CLK and SMODE must be
selected according to the requirements listed in Table 3.
The following points must be taken into account with
regard to the asynchronous protocol.
The protocol starts with a falling edge at the SMODE,

How to enter the trim mode

The status bits to be transmitted to the UZZ9000 are shown in Table 4. Note that a complete protocol has to be sent
before normal operation can be resumed. The trim mode can also be exited by resetting the device. After entering one
of the trim modes and provided there is a dynamic input signal, a square wave output is visible at the terminal T

(pin 22).

Reset

In addition to the external reset pin (pin 6), the UZZ9001
provides an internal power-up/ power-down reset logic
which continuously monitors thesupply voltage.When the
supply voltage increases and reaches a safe level, reset
becomesinactive andthe devicestartsinitialization. When
the supply voltage exceeds the safe voltage level, the
deviceis resetimmediately. Thisinternalreset logiccan be
over-ridden by the external pin RES (pin 6) in all modes
and at any time. The reset pin RES (pin 6) is active when
in the high position. It is internally pulled to ground and
therefore need not be connected if the function is not
required.

the device enters into the diagnostic area if VDD is
disconnected, but not if VSS is disconnected. Similarly, if
the load is apull-up resistor, then the device will enter the
diagnostic area if VSS is disconnected, but not if VDD is
disconnected.It isnot necessary toconnect anoutputload
to the UZZ9000. After recovering from short circuit to
ground or supply voltage, the chip returns undamaged to
the normal operation mode. There is no time limitation
regarding short circuit of V

.

Measurement dynamics

The UZZ9000 includes an on-chip RC Oscillator that
generates the clock for the whole device. Consequently,
no external clock supply is required for the measurement

system. The nominal clock frequency of the on-chip
oscillator is 4 MHz at room temperature. It varies with
temperature change. At −40 °C the clock frequency may
decrease to 2.3 MHz. At higher temperatures however, a
frequency up to 5.7 MHz maybe reached.This influences
the dynamics of measurements.From anapplication point
of view,two different effectshave to be distinguished: The
system delay, which means how long it takes until a
changed input signal is recognized at the output, and the
measurement update rate. The system delay is mainly
caused by the settling time of the low pass decimation
filter, which depends on the maximum frequency content
(shape) of the input signals and the clock frequency. The
following maximum values can be expected for the entire
system delay. The measurement update rate, however,is
directly related to the oscillator frequency. At room
temperature, a new value is available every 0.26 ms.
When taking the entire temperature range into account,
updaterates between0.45 and 0.18 msare possible.(see
Table 5).
