■ GENERAL DESCRIPTION
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.

■ FEATURES
• Internal complete driver and phase logic
• 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
