NJM3770AD3 Overview
NJM3770A 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 NJM3770A is a high power version and pinpatible with the NJM3717.Two NJM3770A and a small number of external ponents form a plete control and drive unit stepper motor systems. Timing pin connect a 56 kΩ resistor and a 820 pF in parallel...
