NJM37770E2
DESCRIPTION
NJM37770 is a stepper motor driver, which consists of a
LS-TTL patible 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 pinpatible with the NJM37717 and also NJM37770 is a high voltage version with NJM3770A. Two NJM37770 and a small number of external ponents form a plete control and drive unit stepper motor systems.
