TB67S158FTG TOSHIBA Bi-CD Integrated Circuit Silicon Monolithic TB67S158FTG1. Summary/Features/AppearanceConstant voltage control DMOS driver incorporating 3 function modes (full parallel input, clockinput, and serial input) and a large mode.SummaryFTG The TB67S158 is a constant voltage control DMOS driver. It can operate maximum of two unipolar stepping motors (max). MODE1: Full parallel input (similar to transistor array) MODE2: CLK input MODE3: Serial input MODE4: Large mode Output voltage of 80V and maximum current of 1.5A are realized by P-WQFN48-0707-0.50-003
