General 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.

Overview

February 1999 PBL 3775/1 Dual Stepper Motor Driver.

Key Features

Dual chopper driver in a single package.
Operation down to -40°C.
750 mA continuous output current per channel.
Low power dissipation, 2.0 W at 2 x 500 mA output current.
Close matching between channels for high microstepping accuracy.
Digital filter on chip eliminates external filtering components.
Plastic 22-pin batwing DIL package, 24-pin SOIC batwing or 28-pin power PLCC. All with lead-frame for heatsinking through PC boar.
