February 1999 PBL 3775, 1 Dual Stepper Motor Driver Description 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, 1 is equipped with a disable input to simplify half-stepping operation. The PBL 3775, 1 contains a clock oscillator, which is comm
