PBL3774-1 driver equivalent, dual stepper motor driver.
* 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 7.
the PBL 3774/1 is equipped with a TTL level compatible Disable input to simplify half-stepping operation.
The circuit i.
The PBL 3774/1 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 3772/1. While all Dual stepper motor drivers are optim.
