NP3775 Bipolar Stepper Motor Drive IC & NP7380 Phase Distribution IC

Nippon Pulse America, Inc., Radford, VA - (May 16, 2007) Nippon Pulse America introduces a bipolar chopper driver chip, NP3775, and a state logic chip (phase distribution chip), NP7380, for use with their tin-can rotary and linear stepper motors.

Nippon Pulse America provides motors, electronics, and engineering support for a complete stepper motor drive system.


o Dual Bipolar chopper drive IC to drive a 2 phase stepper motor

o Full or half step operation - Max output current is 750mA

o Digital filter on chip eliminates external filtering components

o Designed to drive two-phase bipolar stepper motors

o Connects directly to the CPU - chips include a clock oscillator, as well as comparators and flip-flops for switching control

o NP3775D2, DIP package (22-pin) and NP3775E3, EMP package (24-pin) offered for both small quantity and mass productions

o NP7380 state logic chip is a 14-pin EMP package

o RoHS Compliant

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.

The NP3775 driver chip is available in two package sizes, 24-pin EMP (NP3775D2) for mass production, and 22-pin DIP (NP3775E3) for prototyping and small runs. The NP7380 state logic chip is a 14-pin EMP package.

As an integrated manufacturer, Nippon Pulse has the knowledge, capability, and facilities to help OEMs develop motion control solutions with stepper motors and drive electronics.

One hundred piece pricing is $6.49 each for the NP3775D2, $2.70 each for the NP3775E3, and $0.99 each for the NP7380.

Nippon Pulse America, Inc. is the wholly owned American subsidiary of Nippon Pulse Motor Co., Ltd. Nippon Pulse offers various controllers (boards and chips), drivers (boards and chips), motors (tin-can, hybrid, and linear servo), and Engineering Services to help OEMs with almost any motion application.
