TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB6643KQ Full-Bridge DC Motor Driver IC The TB6643KQ is a full-bridge DC motor driver IC employing the MOS process for output power 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. Features  Power supply voltage: 50 V (max)  Output current: 4.5 A (max)  Output ON-resistance: 0.55  (typ.)  PWM control  CW/CCW/Short Brake/Stop modes  Overcurrent shutdown circuit (ISD)  Overvoltage shutdown circuit (VSD)  Thermal shutdown circuit (TSD)  Undervoltage lockout circuit (UVLO)  Dead time for preventing shoot-through current Weight: 2.2 g (typ.
