TLE 4729 G
Application Hints
The TLE 4729 G is intended to drive both phases of a stepper motor. Special care has
been taken to provide high efficiency, robustness and to minimize external components.
Power Supply
The TLE 4729 G will work with supply voltages ranging from 5 V to 16 V at pin
V
S
. Surges
exceeding 16 V at
V
S
wont harm the circuit up to 45 V, but whole function is not
guaranteed. As soon as the voltage drops below approximately 16 V the TLE 4729 G
works promptly again.
As the circuit operates with chopper regulation of the current, interference generation
problems can arise in some applications. Therefore the power supply should be
decoupled by a 0.1
μ
F ceramic capacitor located near the package. Unstabilized
supplies may even afford higher capacities.
Inhibit Mode
In the case of low at all four current program inputs
I
XX the device will switch into inhibit
condition; the current consumption is reduced to very low values.
When starting operation again, i.e. putting at least one
I
XX to high potential, the Error 1
output signals an open load error if the corresponding phase input is high. The error is
reset by first recirculation in chop mode.
Current Sensing
The current in the windings of the stepper motor is sensed by the voltage drop across
R
sense
. Depending on the selected current internal comparators will turn off the sink
transistor as soon as the voltage drop reaches certain thresholds (typical 0 V, 0.07 V,
0.45 V and 0.7 V). These thresholds are not affected by variations of
V
S
. Consequently
instabilized supplies will not affect the performance of the regulation. For precise current
level it must be considered, that internal bounding wire (typ. 60 m
)
is a part of
R
sense
.
Due to chopper control fast current rises (up to 10 A/
μ
s) will occur at the sensing
resistors. To prevent malfunction of the current sensing mechanism
R
sense
should be
pure ohmic. The resistors should be wired to GND as directly as possible. Capacitive
loads such as long cables (with high wire to wire capacity) to the motor should be
avoided for the same reason.
Synchronizing Several Choppers
In some applications synchrone chopping of several stepper motor drivers may be
desirable to reduce acoustic interference. This can be done by forcing the oscillator of
the TLE 4729 G by a pulse generator overdriving the oscillator loading currents
(approximately
±
120
μ
A). In these applications low level should be between 0 V and
0.8 V while high level should between 3 V and 5 V.
