Product Description
www.DataSheet4U.com
The AMIS-3062x is a stepper motordriver family with
position controller and control/diagnostics interface
integrated in one single chip.
The family consists of two products:
• AMIS-30621 with LIN interface, ready to build
dedicated mechatronics solutions connected remotely
with a LIN master.
• AMIS-30622 with SERIAL interface, ready to act as
peripheral device next to a microcontroller.
Protection
• Over-current protection
• Under-voltage management
• Over-voltage protection
• High-temp warning and shutdown
• Low-temp warning
• LIN bus short-circuit protection to supply and ground
Power Saving
• Power-down supply current <50µA
• 5V regulator with wake-up on LIN activity
EMI Compatibility
• Power drivers with slope control
The chip receives high-level positioning instructions
through the interface and subsequently drives the motor
coils until the desired position is reached. The on-chip
position controller is configurable (OTP and Interface)
for different motor types, positioning ranges and
parameters for speed, acceleration and deceleration.
The AMIS-3062x acts as a slave on the bus and the
master can fetch specific status information like actual
position, error flags, etc. from each individual slave
node.
Applications and Benefits
The AMIS-3062x family is ideally suited for small
positioning applications. Target markets include:
automotive (headlamp alignment, idle control, cruise),
industrial equipment (lighting, fluid control, labeling,
process, XYZ tables) and building automation (HVAC,
surveillance, satellite dish positioning). Suitable
applications typically have multiple axes or require
mechatronic solutions with the driver chip mounted
directly on the motor.
The high abstraction level of the products’ command set
reduces the load of the processor on the master side.
Scaling of the application towards number of axes is
straight-forward: hardware - and software designs are
extended in a modular way, without severely effecting the
demands on the master microcontroller. The bus structure
simplifies PCB track-layout and/or wiring architectures.
Microstepping operation removes the design trade-off
between minimal operation speed and avoiding the risk of
noise and step-loss due to resonance phenomena. The
stall-detection feature (optional) offers silent, yet accurate
position-calibrations during the referencing run and allows
semi-closed loop operation when approaching the
mechanical end-stops.
All these benefits result in reduced system-cost and time-
to-market and improved technical performance.
