PBL3774 - Dual Stepper Motor Driver

This page provides the datasheet information for the PBL3774, a member of the PBL3774-1 Dual Stepper Motor Driver family.

Description

The PBL 3774/1 is a switch-mode (chopper), constant-current driver IC with two channels, one for each winding of a two-phase stepper motor.

The circuit is similar to Ericsson´s PBL 3771/1 and PBL 3772/1.

February 1999 PBL 3774/1 Dual Stepper Motor Driver Description The PBL 3774/1 is a switch-mode (chopper), constant-current driver IC with two channels, one for each winding of a two-phase stepper motor. The circuit is similar to Ericsson´s PBL 3771/1 and PBL 3772/1. While all Dual stepper motor drivers are optimized for microstepping applications, the PBL 3774/1 is equipped with a TTL level compatible Disable input to simplify half-stepping operation. The circuit is well suited for microstepping applications together with the matching dual DAC (Digital-to-Analog Converter) PBM 3960/1. A complete driver system consists of these two ICs, a few passive components and a microprocessor for generation of the proper control and data codes required for microstepping.
