资 源 简 介

PBD 3517/1 is a bipolar, monolithic, integrated circuit, intended to drive a stepper motorin a unipolar, bilevel way.One PBD 3517/1 and a minimum of external components form a complete controland drive unit for LS-TTL- or microprocessor-controlled stepper motor system forcurrents 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. Thismeans that a high voltage pulse is applied to the motor winding at the beginning of astep, in order to give a rapid rise of current.
