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 pincompatible with the NJM37717and also NJM37770 is a high voltage version with NJM3770A. Two NJM37770 and small number of external components form a complete control and drive unit stepper motor systems.
