Full-Bridge DC Motor Driver IC: TB6640FTG
The TB6640FTG 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 Stand-by.
Features
- Power supply voltage : 40 V (max)
- Output current : 3 A (max)
- Direct PWM control
- PWM constant-current control
- CW/CCW/Short Brake/Stand-by modes
- Overcurrent shutdown circuit (ISD)
- Thermal shutdown circuit (TSD)
- Undervoltage lockout circuit (LVD)
- Dead time for preventing shoot-through current
