DUAL STEPPER MOTOR DRIVER

GENERAL DESCRIPTION
I
PACKAGE OUTLINE
The NJM3777 is a switch-mode (chopper), constant-current
driver with two channels: one for each winding of a two-phase
stepper motor. The NJM3777 is equipped with a Disable input
to simplify half-stepping operation. The NJM3777 contains a
clock oscillator, which is common for both driver channels, a
set of comparators and flip-flops implementing the switching
control, and two output H-bridges, including recirculation
diodes. Voltage supply requirements are + 5 V for logic and +
10 to + 45 V for the motor. Maximum output current is 900mA
per channel.
