NJM3775
DUAL STEPPER MOTOR DRIVER
I
GENERAL DESCRIPTION
I
PACKAGE OUTLINE
The NJM3775 is a switch-mode (chopper), constant-
current driver with two channels: one for each winding
of a two-phase stepper motor. NJM3775 is equipped
with a Disable input to simplify half-stepping operation.
The NJM3775 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
750mA per channel.
