DESCRIPTION
The IC is developed for automotive applications. The stepper mo-
tor driver is optimized to drive SAIA stepper motors, but is also
verified with several bipolar stepper motors in the market. A
stalled detection is fully integrated and does not need a shunt
resistor. With a configuration bit it is possible to decide whether
to stop the movement or not in case of a stalled situation.
With the blocking recognition capability no additional end-
switches are needed, system noise is reduced, initialization is
faster and mechanical problems do not lead to problems in the
motor.
When up to
32
ASICs can be used on one bus; whereby the
5
bit
address of each chip is stored in EEPROM cells. The chip can pro-
gram itself when triggered with the suitable command.
The IC allows to give movement tasks with up to
4096
steps
in each direction. There is a one task stack which allows you to
change speed settings smoothly.
