* Digi

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.
