TB6641FG Datasheet Full-bridge DC Motor Driver Ic

Manufacturer: Toshiba

Overview: TB6641FG/FTG TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB6641FG/FTG Full-Bridge DC Motor Driver IC The TB6641FG/FTG is a full-bridge DC motor driver with MOS output transistors. The low ON-resistance MOS 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.
