STMicroelectronics L6482 cSPIN™
Microstepping Motor Controller
STMicroelectronics L6482 cSPIN Microstepping Motor Controller is an advanced fully integrated solution suitable for driving two-phase bipolar stepper motors with microstepping. It integrates a dual full-bridge gate driver for N-Channel MOSFET power stages with embedded non-dissipative 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 and motor stall) make the L6482 “bullet proof”, as required by the most demanding motor control applications.
