Toshiba Launches DC Brush Motor Driver ICs for Industrial Equipments Supporting High Current and Voltage
The Industry's First Monolithic ICs Realizing 10A Output Current and 50V Withstand Voltage
TOKYO--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.
Key Specifications
*Product Name TB67H303HG
*Power Supply Voltage Absolute maximum rating: 50V
*Output Current Absolute maximum rating: 10.0A
*Functions Control single brush motor (Forward, Reverse, Short brake, and Stop)
*Other Features Built-in standby function
Constant current PWM mode is selectable, in addition to the standard direct PWM mode.
Built-in abnormality detection functions (Thermal shutdown circuit, Over current detection, and Undervoltage lockout circuit)
Power supply applying sequence is free by single power driving.
*Package HZIP25

Featured Product
Schmalz Technology Development - Vacuum Generation without Compressed Air - Flexible and Intelligent
• Vacuum generation that's 100% electrical;
• Integrated intelligence for energy and process control;
• Extensive communication options through IO-Link interface;
Schmalz already offers a large range of solutions that can optimize handling process from single components such as vacuum generators to complete gripping systems. Particularly when used in autonomous warehouse, conventional vacuum generation with compressed air reaches its limits. Compressed air often is unavailable in warehouses. Schmalz therefore is introducing a new technology development: a gripper with vacuum generation that does not use compressed air. The vacuum is generated 100% electrically. This makes the gripper both energy efficient and mobile. At the same time, warehouses need systems with integrated intelligence to deliver information and learn. This enables the use of mobile and self-sufficient robots, which pick production order at various locations in the warehouse. Furthermore, Schmalz provides various modular connection options from its wide range of end effectors in order to handle different products reliably and safely.
