Panasonic AN44183A Microstepping Motor Driver is a two channel H-bridge driver with a bipolar stepping motor that can be controlled by a single driver LSI. Available in a 56 pin plastic small outline package (SOP) with heat sink package, the AN44183A Microstepping Motor Driver offers a built-in decoder for micro steps and a 3.3V power supply with ±3% accuracy. The driver also includes mix decay control, malfunction prevention, home position, standby, over-current protection (OCP), under voltage lockout (UVLO), thermal protection (TSD), and abnormal detection output (NFAULT) functions for internal protection of the IC.
