STMicroelectronics' L6472 dSPIN Fully Integrated Microstepping Motor Driver, realized in analog mixed signal technology, is an advanced fully integrated solution suitable for driving two-phase bipolar stepper motors with microstepping. It integrates a dual low RDS(on) DMOS full bridge with all of the power switches equipped with an accurate on-chip current sensing circuitry suitable for non-dissipative current control and overcurrent protection. Thanks to a new current control, a 1/16 microstepping is achieved through an adaptive decay mode which outperforms traditional implementations. The digital control core can generate user defined motion profiles with acceleration, deceleration, speed or target position, easily programmed through a dedicated register set. A very rich set of protections (thermal, low bus voltage, overcurrent) makes the L6472 "bullet proof", as required by the most demanding motor control applications.
