PBL3774-1 Datasheet (Ericsson) - Dual Stepper Motor Driver

PBL3774-1, Dual Stepper Motor Driver

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/
