This bipolar chopper driver chip, NP3775, and state logic chip (phase distribution chip), NP7380, are offered for use with the company’s tin-can rotary and linear stepper motors. The firm provides motors, electronics, and engineering support for a complete stepper motor drive system. Features of these products include dual bipolar chopper drive IC to drive a 2 phase stepper motor, full or half step operation (max. output current is 750 mA), digital filter on chip eliminates external filtering components, designed to drive two-phase bipolar stepper motors, and connects directly to the CPU (chips include a clock oscillator, as well as comparators and flip-flops for switching control). The NP3775 driver chip connects to a CPU that has four general outputs. It also connects to a CPU through the NP7380 state logic chip (phase distribution chip) which decreases the burden on the CPU.
