Overview
February 1999 PBD 3517/1 Stepper Motor Drive Circuit Description PBD 3517/1 is a bipolar, monolithic, integrated circuit, intended to drive a stepper motor in a unipolar, bilevel way.
One PBD 3517/1 and a minimum of external components form a complete control and drive unit for LS-TTL- or microprocessor-controlled stepper motor system for currents up to 500mA.
The driver is suited for applications requiring least-posssible RFI.
Motor performance can be increased by operating in a bilevel drive mode.
This means that a high voltage pulse is applied to the motor winding at the beginning of a step, in order to give a rapid rise of current.
Key Features • Complete driver and phase logic on chip • 2 x 350 mA continuous-output current • Half- and full-step mode generation • LS-TTL-compatible inputs • Bilevel drive mode for high step rates • Voltage-doubling drive possibilities • Half-step position-indication output • Minimal RFI • 16-pin plastic DIP package or 16 pin small outline wide body VCC VSS PQR LB STEP PB2 INH OA OB PA2 PA1 GND 16-pin plastic DIP 16-pin SO (wide body) Figure 1.
