PBL3776-1, Dual Controller IC for High Current Stepper Motor Applications

The PBL 3776/1 is a switch-mode (chopper), constant-current controller IC intended for controlling external transistors in a high current stepper motor application.The IC has two channels one for each winding of a two-phase stepper motor.

The circuit is similar to Ericsson´s PBL 3775/1.
