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.
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.
