integrated transceiver motor driverON Semiconductor’s AMIS-30523 integrates a stepper motor driver and CAN transceiver in a single package, two-die device. This configuration can be used to control multiple motors of the same type on a single bus, and it provides space savings in designs where PCB real estate is limited or where a single PCB mounted on the back of the motor is employed. Typical applications include general purpose stepper motors in automotive, industrial, medical and marine environments. The 1 megabit per second (Mb/s) high-speed AMIS-30523 offers seven step modes from full step up to 32 micro-steps. The new device uses a 5-bit current digital-to-analog converter (DAC) to provide a programmable peak current of up to 1.6 amperes (A). Additional features include an on-chip voltage regulator and current translator, an SPI interface, reset-output, and watchdog reset. The IC is housed in a QFP-52 package measuring 8 mm x 8 mm with an overall nominal height of just 0.7 mm and is fully compatible with ISO 11898-2.
