Full-Bridge DC Motor Driver IC
TB6569FG
The TB6569FG 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.
Features

• Output current: 4.5 A (max)
• Direct PWM control
• PWM constasnt-current control
• CW/CCW/Short Brake/Stop modes
• Overcurrent shutdown circuit (ISD)
• Overcurrent detection threshold control
