General Description
This system-in-a-chip IC controls bipolar stepper actuators
with current-choppered micro-stepping. The IC is controlled
by a LIN2.x interface. It’s LIN-address can calculated by the
“auto-addressing” feature (called “SNPD” in official LIN-spec-
ification). Alternatively the IC can be controlled by a PWM-in-
terface, with diagnosis feedback. The integrated sensor-less
“stall-detection” detects mechanical end-positions and stops
the motor to reduce acoustical noise during initialization
runs. The calculating heart is an 8-bit controller which is as-
sisted by powerful circuitry. For absolute precise positioning,
up to 3 Hall-sensors or potentiometers can read out.
The IC can also drive up to 3 DC motors or other loads. ICs
with FLASH-memory are programmable via JTAG interface or
LIN in normal or high speed mode. The IC is available with
standard firmware as well as with a development system for
individual firmware.
