NJM6219
STEPPER MOTOR DRIVER
■ GENERALDESCRIPTION
■ PACKAGE OUTLINE
The NJM6219 is a stepper motor driver, which consists of a
LS-TTL compartible logic input stage, off time control circuits
and a pair of high power H-bridges and protection diodes.
The output current is up to 1000mA.
The NJM6219 with small number of external components
conforms a complete control and drive unit for stepper motor
systems.
.
■ FEATURES
• Switched mode bipolar constant current drive
• Wide voltage range 4 to 45V
• Wide range of current control 5 to 1000mA
• Half- step and full-step operation
• Thermal overload protection
• Package SOP24-E3 JEDEC 300mil
