Toshiba Launches DC Brush Motor Driver ICs for Industrial Equipments Supporting High Current and Voltage


March 24, 2014 - Tokyo, Japan

Toshiba Corporation (TOKYO:6502) today announced the launch of “TB67H303HG”, a one-channel DC brush motor driver IC for industrial equipment. The product is the industry’s first1 monolithic2 IC to realize 10A output current and 50V withstand voltage. Mass production shipments start today.

High output current and voltage are required for motor driver circuits in industrial equipment. That makes it difficult to design circuits with a single driver IC, as the high current generates heat. Multiple discrete semiconductors are generally used in order to reduce heat generation in each component.

 

“TB67H303HG” adopts the latest high voltage analog process, reducing on resistance to 80% that of its predecessor3, to 0.2Ω or less. The new IC contributes to the reduction of discrete semiconductor devices, and to simplification and downsizing of applications.

 

The IC also incorporates abnormality detection functions, contributing to improved safety for high current motor drive.

 

Key Features

 
  • Driving mode
    Selectable from two driving modes: standard direct PWM mode, or newly adopted constant current PWM mode.
  • High current drive
    Low on resistance of 0.2Ω or less (sum of upper and lower) realizes absolute maximum output current of 10A.
  • Built-in abnormality detection functions
    Incorporates a thermal shutdown circuit, over current detection, and undervoltage lockout (UVLO) circuit, which improve the safety of the high current motor drive.

Applications

 

Industrial equipments, banking terminals such as banknote recognition systems, home appliances including sewing machines, and office automation equipment.
