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.
The close match between the two driver channels guarantees consistent output
current ratios and motor positioning accuracy.
