PBL 3775/1  
Dual Stepper Motor Driver  
Description  
Key Features  
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.  
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.  
Voltage supply requirements are + 5 V for logic and + 10 to + 45 V for the motor.  
The close match between the two driver channels guarantees consistent output  
current ratios and motor positioning accuracy.  
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 board  
copper.
