NJM37770
STEPPER MOTOR DRIVER
s GENERAL DESCRIPTION
NJM37770 is a stepper motor driver, which consists of a
LS-TTL compatible logic input stage, a current sensor, a
monostable multivibrator and a high power H-bridge output
stage. The NJM37770 is a high power version and pin-
compatible with the NJM37717and also NJM37770 is a
high voltage version with NJM3770A. Two NJM37770 and
a small number of external components form a complete
control and drive unit stepper motor systems.
