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.
