Dialog adds high-voltage GreenPAK IC for motor drives

Dialog Semiconductor plc has introduced its first motor drive configurable mixed-signal IC (CMIC) with both configurable logic and configurable analog with high-voltage outputs. The new SLG47105 device is part of Dialog’s GreenPAK portfolio and provides a one-time NVM programmable option for designers looking to integrate both digital and analog system functions in consumer and industrial motor applications.

Housed in a tiny 2 × 3-mm QFN package, the SLG47105 is capable of driving two brushed DC motors, a single stepper motor, a solenoid, or any other load requiring up to 1.5-A RMS current per output and an operating voltage up to 13.2 V. In addition to standard protection features such as overtemperature, undervoltage, and overcurrent protection, the SLG47105 also includes configurable digital and analog resources that allow the user to create a customized protection and motor control scheme with current or voltage regulation, stall detection, or soft motor start to enable higher system reliability and more efficient battery usage.

The SLG47105 includes low-power-consumption functions including internal voltage references, power-on reset, an oscillator, and more advanced digital resources, like pulse-width modulators. The current consumption in standby mode for the entire chip is as low as 70 nA for a longer battery life and can deliver a lower overall system current consumption versus more discrete solutions, according to Dialog.

The company is also releasing a new update for the GreenPAK Designer software package that enables users to configure, optimize, simulate, test, and evaluate GreenPAK designs. The update adds simulation capabilities to incorporate external components, ranging from passive devices like shunt resistors to more complex devices like motors, which will further reduce development time and simplify the design process across the GreenPAK portfolio.

The SLG47105 is sampling now and will be in production in the second half of 2020. An evaluation board including both a brushed and stepper motor is now available for the SLG47105 via Dialog’s GreenPAK online store.
