■ GENERAL DESCRIPTION
NJM3717 is a stepper motor diver, which consists of a LS-TTL compatible logic input stage, a current sensor, a monostable multivibrator and a high power H-bridge output stage with built-in protection diodes.
The output current is up to 1200mA. Two NJM3717 and a small number of external components form a complete control and drive unit for stepper motor systems.

■ FEATURES
• Half-step and full-step modes
• Switched mode bipolar constant current drive
• Wide range of current control 5 - 1200 mA
• Wide voltage range 10 - 50 V
• Thermal overload protection
• Packages DIP16 / PLCC28 / EMP20
