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.
