PBL3775-1 Datasheet (Ericsson) - Dual Stepper Motor Driver

PBL3775-1, Dual Stepper Motor Driver

The PBL 3775/1 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 3773/1.

While several of Ericsson´s dual stepper motor drivers are optimized for micro-stepping applications, PBL 3775/

PBL3775-1 Features

* Dual chopper driver in a single package.
