PBL3775-1 - 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.

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.

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 common for both driver channels, a set of comparators and flip-flops implementing the switching control, and two output H-bridges, including recirculation diodes. Voltage supply requirements are + 5 V for logic and + 10 to + 45 V for the motor.
