Overview

TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB6643KQ Full-Bridge DC Motor Driver IC The TB6643KQ 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.

Key Features

Power supply voltage: 50 V (max).
Output current: 4.5 A (max).
Output ON-resistance: 0.55  (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. ) TB6643KQ Note: The following conditions apply to solderability: About solderability, followin.
