Description: Dual Stepper Motor Driver

Features

* Dual chopper driver in a single package.
* Operation at -40 °C.
* 1000 mA continuous output current per channel.
* Low power dissipation, 2.6 W at 2 x 750 mA output current.
* Close matching between channels for high microstepping accuracy.
* Special

Applications

* the PBL 3774/1 is equipped with a TTL level compatible Disable input to simplify half-stepping operation. The circuit is well suited for microstepping applications together with the matching dual DAC (Digital-to-Analog Converter) PBM 3960/1. A complete driver system consists of these two ICs, a few
