Overview

TB6641FG/FTG TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB6641FG/FTG Full-Bridge DC Motor Driver IC The TB6641FG/FTG 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.

Key Features

  • Power supply voltage : 50 V (max).
  • Output current : 4.5 A (max).
  • Direct PWM control.
  • PWM constant-current control.
  • CW/CCW/Short Brake/Stop modes.
  • Overcurrent shutdown circuit (ISD).
  • Overcurrent detection time control.
  • Overvoltage shutdown circuit (VSD).
  • Thermal shutdown circuit (TSD).
  • Undervoltage lockout circuit (UVLO).
  • Dead time for preventing shoot-through current TB6641FG: Weight.
