TB6568KQ
Full-Bridge DC Motor Driver IC
The TB6568KQ 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: 3 A (max)
Output ON-resistance: 0.55 Ω (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.)
