General Description
The AMIS-42671 CAN transceiver with autobaud is the interface between a controller area network (CAN) protocol controller and the physical bus. It may be used in both 12V and 24V systems. The transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller. Due to the wide common-mode voltage range of the receiver inputs, the AMIS-42671 is able to reach outstanding levels of electromagnetic susceptibility (EMS). Similarly, extremely low electromagnetic emission (EME) is achieved by the excellent matching of the output signals.
The AMIS-42671 is primarily intended for industrial network applications where long network lengths are mandatory. Examples are elevators, in-building networks, process control and trains. To cope with the long bus delay the communication speed needs to be low. AMIS-42671 allows low transmit data rates down 10 Kbit/s or lower. The autobaud function allows the CAN controller to determine the incoming baud rate without influencing the CAN communication on the bus.

AMIS-42671 - High-Speed CAN Transceiver

General Description
The AMIS-42675 CAN transceiver is the interface between a controller area network (CAN) protocol controller and the physical bus. It may be used in both 12V and 24V systems. The transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller.
The AMIS-42675 is the low power member of the CAN high-speed transceiver family and offers the following additional features:
• Ideal passive behaviour when supply voltage is removed

AMIS-42675 - High-Speed Low Power CAN Transceiver

Product Description
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.
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 smal 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 timeto- market and improved technical performance.
