STMicroelectronics L6482 cSPIN Microstepping Motor Controller

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.

EVAL6482H Demonstration Board

STMicroelectronics EVAL6482H Demonstration Board is a high power microstepping motor driver. In combination with the STEVAL-PCC009V2 communication board and the evaluation software, the board allows the user to investigate all the features of the L6482 device. In particular, the board can be used to check the advanced current control and to regulate the L6482 parameters in order to fit the application requirements. The EVAL6482H supports the daisy chain configuration making it suitable for the evaluation of the L6482 in multi-motor applications.
