PBL 3773/1  
Dual Stepper Motor Driver  
Description  
Key Features  
The PBL 3773/1 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 3771/1 and PBL 3775/1. While all Dual stepper motor drivers are  
optimized for microstepping applications, PBL 3773/1 is also equipped with a Disable  
input to simplify half-stepping operation.  
The circuit is well suited for microstepping applications. The current control inputs  
are low current, high impedance inputs, which allows the use of unbuffered Digital-to-  
Analog converters or external high resistive resistor divider networks.  
The PBL 3773/1 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.  
•
•
Down to -40°C operation  
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  
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.  
High impedance current control  
inputs  
Digital filter on chip eliminates  
external filtering components.
