TB67H301FTG TOSHIBA Bi-CDMOS Integrated Circuit Silicon Monolithic TB67H301FTG Full-Bridge DC Motor Driver IC The TB67H301FTG is a full-bridge DC motor driver with DMOS output transistors. The low ON-resistance DMOS process and PWM control enables driving DC motors with high thermal efficiency. Four operating modes are selectable via IN1 and IN2: clockwise (CW), counterclockwise (CCW), Short Brake and Stop. P-WQFN24-0404-0.50-004: Weight: 0.036 g (typ.)
