Normal Operating Mode (regulation loop)
The regulation loop of the AS8410 consist of the following functional blocks:
1. Analogue / Digital Interface with signal conditioning (set value input / failure signal
output
IN
, modus input
MODE
and low pass filter input
Cint2)
2. Regulator characteristic generator (high resolution of the set value for set
values < 50 % and lower resolution for set values 50 % … 100 %)
3. Difference generator at the pin
Cint1
(V
Cint1
= (set value) – (motor current value) )
4. PWM generator (controlled by the voltage V
Cint1
and the 20 kHz oscillator)
5. Power FET driver with slew rate regulation controlling the external power FET gate
connected at pin
OUT
6. Motor current measurement unit (measuring and converting the voltage over the ex-
ternal resistor R
meas
connected at the pins
CMp
and
CMn
)
7. Oscillator (20 kHz) and reference current generator (regulated V
OSC
= 1 V at pin
OSC
with external resistor R
osc
= 100 k
)
8. Charge pump with external capacitors at the pins
Pump_ctrl
and
Vpump
9. 5V-regulator with bandgap reference
4.1.1
Analogue / Digital Interface, Signal Conditioning
This interface consists of the three pins
MODE
,
IN
and
Cint2
. The interface sets the operating
mode by the signal MODE, monitors and converts the input set value at the pin
IN
and drives
the pin
IN
to the low level in case of a detected failure in operating mode 1.
In operating mode 1 (OM1) the incoming low frequency PWM signal is converted in a dc voltage
by switching a current I
cint2
= 10
μ
A with the incoming duty ratio to the pin
Cint2
with R
int2
/ C
int2
(typical: 200 k
/ 2.2
μ
F). V
cint2
must be in the range V
cint2
= 0 … 2 V.
The monitor of the set value V
Cint2
generates two internal logical signal P00 and P10 to treat the
sleep / wake function and the input failure detection in operating mode 1, the hysteresis of these
detections is given in Fig. 4.2.
