Toshiba TB67H482FNG Single H-Bridge Brush Motor Driver IC
Toshiba TB67H482FNG Single H-Bridge Brush Motor Driver IC is a high-performance device designed for a wide range of motor control applications. Built using Toshiba’s advanced BiCD process, the Toshiba TB67H482FNG integrates DMOSFETs to deliver high efficiency and compactness, supporting motor drive voltages up to 50V and output currents up to 5A (absolute maximum ratings). The device features a PWM-controlled constant current drive system, enabling precise control of motor speed and torque, which is essential for applications such as office automation equipment, home appliances, and industrial tools.
The Driver IC also includes multiple built-in protection functions, including thermal shutdown (TSD), overcurrent detection (ISD), and undervoltage lockout (UVLO), to ensure safe and reliable operation. With flexible decay modes and a low-power sleep function, the TB67H482FNG is well-suited for battery-powered and energy-efficient designs, making it a versatile choice for modern motor control systems.
