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 EricssonĀ“s PBL 3771/1 and PBL 3772/1. While all Dual stepper motor drivers are optimized for microstepping applications, the PBL ...
