STMicroelectronics L6480 Microstepping Motor Driver
STMicroelectronics L6480 Microstepping Motor Driver is an advanced fully integrated solution suitable for driving two-phase bipolar stepper motors with microstepping. The driver integrates a dual full bridge gate driver for N-channel MOSFET power stages with embedded non-dissipative overcurrent protection. With a unique voltage driving mode which compensates for BEMF, bus voltage and motor winding variations, the microstepping of a true 1/128-step resolution is achieved.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 and motor stall) make the L6480 a rugged solution, as required by demanding motor control applications.
