Industry's first monolithic integrated circuit supports 10A output current and 50V voltage
TOKYO — (Toshiba TOKYO: 6502) announced the launch of the single-channel DC brush motor driver IC “TB67H303HG†for industrial equipment. This product is the industry's first 1 single-chip 2 integrated circuit that can support 10A output current and 50V voltage. Mass production shipments will begin today.
Industrial equipment motor driver circuits require high output current and voltage. This makes it difficult to design a circuit that includes a single-drive integrated circuit because high currents generate heat. To reduce the amount of heat generated by each component, multiple independent semiconductors are typically used.
The “TB67H303HG†uses the latest high voltage analog process to reduce the on-resistance to 80% (0.2 Ω or less) of its previous version 3. This new integrated circuit helps reduce the number of independent semiconductor devices and simplifies application and size.
The IC also features anomaly detection to help improve the safety of high current motor drives.
Main characteristics
Drive mode
Two selectable drive modes: standard direct PWM mode or new constant current PWM mode.
High current drive
Low on-resistance (upper and lower sum) of 0.2Ω or less supports 10A absolute maximum output current.
Built-in anomaly detection
Integrated thermal protection circuitry, overcurrent detection and undervoltage lockout (UVLO) circuitry enhance the safety of high current motor drives.
application
Industrial equipment, banknote identification systems and other bank terminals, sewing machines and other household appliances and office automation equipment.
