TOSHIBA Bi-CDMOS Integrated Circuit Silicon Monolithic TB6640AFTG TB6640AFTG Full-Bridge DC Motor Driver IC The TB6640AFTG 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. Features • Power supply voltage : 40 V (max) • Output current : 3 A (max) • Direct PWM control • PWM constasnt-current control • CW/CCW/Short Brake/Stop • Overcurrent shutdown circuit (ISD) • Thermal shutdown circuit (TSD) • Undervoltage lockout circuit (LVD) • Dead time for preventing shoot-through current Weight: 0.1g (typ.
