1 Features
This new generation of trench MOSFETs utilizes a unique structure that combines the benefits of low
on-resistance with fast switching speed. Their unique high density four device package makes them
ideal for high efficiency, low voltage, power management applications such as stepper motor drivers
or DC motor drivers, using only a single package. Its low gate charge makes it an ideal power driver
for the TMC239A and TMC249A family of stepper motor drivers. Using only two of these transistor
packages, and the miniaturized TMC239A-LA or TMC249A-LA, a 1.5A (continuously) / 2.5A (current for 5
seconds) stepper driver can be build in the size of a stamp, using only three inexpensive devices.

6.2
DC motor control with TMC239 and TMC32NP2-SM8
The TMC239 uses a constant current chopper principle, which is optimum for driving stepper motors.
When operating DC motors with constant current, they provide a roughly constant torque. This in
other words means, that velocity is very dependent upon mechanical load on the motor. Normally a
velocity control is desired, with a torque limit as an add on. The TMC239 can do both! All of its
advanced protection and diagnostic features can be used. One TMC239 can control two DC motors!
This solution uses the SPI interface of the TMC239 and allows full access to all of its features (Figure
6.2). The CPU provides three PWM signals to the TMC239: It directly controls the chopper clock (OSC)
and uses INA / INB to provide a PWM signal for motor 1 and motor 2 (please keep in mind that the
voltage for INA / INB should not be higher than 3V). The chopper clock can be in a range of a few
kilo Hertz to a few ten kHz.
Copyright © 2007, TRINAMIC Motion Control GmbH & Co. KG
TMC32NP2-SM8 Manual (V1.03 /16 Aug 2007)
15
The PWM signal for motor 1 is related to the rising edge of the OSC pin (see Figure 6.3), while the
PWM signal for motor 2 (if used) is related to the falling edge. The motor chopper is on, beginning
from its related OSC edge until the processor switches the related INA / INB input to low. Required
low time for INA / INB is 3µs or more. INA / INB shall return to high latest at the next related OSC
edge. The resulting chopper on time controls the motor velocity. Please never let the OSC pin PWM
output tri-stated. Provide a 10K pullup if this can not be guaranteed.
The motor torque is controlled by the current setting. The current calculation is identical as for a
stepper motor: It is given via the digital current control bits in combination with the sense resistors
and the INA / INB voltage divider control. You can try with slow or mixed decay setting for this
mode. The motor direction is controlled by the SPI PHA / PHB bits. The motor can be stopped by
programming the related DAC bits to zero. The three required PWM signals can be generated via a
microcontroller with capture / compare unit, or using a single shot timer and interrupt operation.
This chopper scheme is the standard for DC motors. The TMC239 adds torque control and protection
and diagnostic features.
