TB6568KQ is a full bridge DC motor drive IC, with output power transistors using MOS technology. Low conductivity MOS technology and PWM control can drive DC motors with high thermal efficiency. Four operating modes can be selected through IN1 and IN2: clockwise (CW), counterclockwise (CCW), short brake, and stop. Features • Power voltage: 50 V (maximum) • Output current: 3 A (maximum) • Output conducting resistance: 0.55 Ω (typical) • PWM control • CW/CCW/Short circuit braking/stop mode • Over current shutdown circuit (ISD) • Over voltage shutdown circuit (VSD) • Thermal shutdown circuit (TSD) • Under voltage lockout circuit (UVLO) • Dead time to prevent breakdown current
