NJM3517

NJM3517 STEPPER MOTOR CONTROLLER / DRIVER s 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. s FEATURES Internal complete driver and phase logic Continuous-output current 2 x 350mA NJM3517D2 NJM3517E2 s PACKAGE OUTLINE 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 s BLOCK DIAGRAM VCC VSS NJM3517 POR RC Mono F-F LA LB STEP DIR HSM INH OA OB Phase Logic PA PB2 PB PB1 PA2 PA1 GND Figure 1.
