NJM3717 STEPPER MOTOR DRIVER ■ GENERAL DESCRIPTION The 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. ■ PACKAGE OUTLINE ■ FEATURES ● Half-step and full-step modes ● Switched mode bipolar constant current drive ● Wide range of current control 5 to 1200mA ● Wide voltage range 10 to 50V ● Thermal overload protection ● Packages DIP16-D2 / PLCC28-M2 SOP20 JEDEC 300mil NJM3717D2 ( DIP16 ) NJM3717E2 ( SOP20 ) NJM3717FM2 ( PLCC28-M2 ) ■ BLOCK DIAGRAM Figure 1.
