STEPPER MOTOR DRIVER
s
GENERAL DESCRIPTION
NJM37717 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.
NJM37717 is a high voltage version and pin compatible with
NJM3717. The output current is up to 1200mA. Two NJM37717
and a small number of external components from a complete
control and drive unit for stepper moter system.
