The TB6560AHQ/AFG is a PWM chopper-type stepping motor driver IC designed for sinusoidal-input microstep control of bipolar stepping motors. The TB6560AHQ/AFG can be used in applications that require 2-phase, 1-2-phase, 2W1-2-phase and 4W1-2-phase excitation modes. The TB6560AHQ/AFG is capable of low-vibration, high-performance forward and reverse driving of a two-phase bipolar stepping motor using only a clock signal.

The L6470 dSPIN motor driver, using analog and mixed-signal technology, is an advanced fully integrated solution suitable for driving 2-phase stepper motors with micro-stepping. It integrates a dual low RDS(on) DMOS full bridge with all of the power switches equipped with accurate on-chip current sensing circuitry suitable for non-dissipative current control and overcurrent protection. A unique control system ensures 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. All commands and data registers, including those used to set analog values (such as current control value, current protection trip point, dead time, PWM frequency) are sent through a 5 Mbit/s SPI.
A rich set of protection features (thermal, low bus voltage, overcurrent, motor stall) allows the design of fully-protected applications, as required by the most demanding motor control applications.
