NJM3517
STEPPER MOTOR CONTROLLER / DRIVER
s GENERAL DESCRIPTION
s PACKAGE OUTLINE
NJM3517 is a stepper motor controller/driver, which requires
minimum of external components and drive currents up to 500mA.
The NJM3517 is suited for applications requiring least-possible RFI.
Operating in a bi-level drive mode can increase motor performance;
high voltage pulse is applied to the motor winding at the beginning
of a step, in order to give a rapid rise of current.
s FEATURES
• Internal complete driver and phase logic
NJM3517D2
NJM3517E2
• Continuous-output current 2 x 350mA
• Half- and full-step mode generation
• LS-TTL-compatible inputs
• Bi-level drive mode for high step rates
• Voltage-doubling drive possibilities
• Half-step position-indication output
• Minimal RFI
• Packages DIP16 / EMP16
