Housed in an EMP16 package, the NP2671E2 chip from Nippon Pulse is a high-performance, low-voltage constant voltage driver for stepper motors with unipolar windings. It allows for a maximum motor output of 60V and a maximum current of 500mA. The pulse input (Pulse&Dir) system enables easy switching between half and full step modes. With the 60V maximum phase output, the user cannot exceed the phase output margin of the motor, which is a common problem with motors with unipolar windings. Allowing high-speed motor applications, the maximum phase output also simplifies the design control circuits during the phase turnoff. Since the NP2671E2 employs a general-purpose Pulse&Dir controller, it can easily control a stepper motor when used in conjunction with a pulse generator. It also has built-in phase logic for optimal control of the stepper motor. Other features of the driver chip include 2-channel x 500mA continuous output current, an output current of 0.35A/phase, and acceleration current of 0.5A, external phase logic reset terminal (RESET), a thermal shutdown circuit, and a phase origin monitoring output terminal (MO).
