PBD35171 - Stepper Motor Drive Circuit

Datasheet Summary

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.

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.

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.
