STMicroelectronics L9942 Stepper Motor Driver

STMicroelectronics L9942 Stepper Motor Driver is an integrated stepper motor driver for bipolar stepper motors with microstepping and programmable current profile look-up-table to allow a flexible adaptation of the stepper motor characteristics and intended operating conditions. It is possible to use different current profiles depending on target criteria: audible noise, vibrations, rotation speed or torque. The decay mode used in PWM-current control circuit can be programmed to slow-, fast-, mixed-and auto-decay. In auto-decay mode device will use slow decay mode if the current for the next step will increase and the fast decay or mixed decay mode if the current will decrease. The programmable stall detection is useful in case of head lamp leveling and bending light application, by preventing to run the motor too long time in stall for position alignment. If a stall is detected, the alignment process is closed and the noise is minimized.
