The L6472 is a fully integrated microstepping motor driver designed for two-phase bipolar stepper motors. It operates within a voltage range of 8 to 45 V and can deliver a peak output current of 7.0 A, with a continuous output current of 3.0 A. The device features low RDS(on) power MOSFETs and supports up to 1/16 microstepping through an adaptive decay mode, enhancing performance compared to traditional drivers. The L6472 includes a digital control core that allows for programmable motion profiles, including acceleration, deceleration, speed, and target position, which can be configured via a standard 5-Mbit/s SPI interface. It is equipped with comprehensive protection features, including thermal protection, low bus voltage detection, and non-dissipative overcurrent protection, making it suitable for demanding motor control applications. The device is available in an HTSSOP28 package, ensuring a compact footprint for integration into various designs.
