choice for applications, where a reference
point is needed, but where a switch is not
desired. Its ability to predict an overload
m a kes the TMC249 an optimum
choice for drives, where a high relia-
bility is desired. Internal DACs allow
microstepping as well as smart cur-
rent control. The device can be controlled by
a serial interface (SPI) or by analog / digi-
tal input signals. Short circuit, temperature,
undervoltage and overvoltage protection are
integrated.
The TMC249 is a dual full bridge driver IC
for bipolar stepper motor control applica-
tions. The TMC249 is realized in a HVC-
MOS technology and directly
drives eight external Low-RDS-ON
high efficiency MOSFETs. It sup-
ports up to 4000mA coil current.
With additional drivers, motor current and
voltage can be increased. The driver tran-
sistors can be chosen depending on output
current or environment temperature. The
integrated unique sensorless stall detec-
tion (pat.fi.) StallGuard makes it a good
