H-bridge motor driver for high-torque applications

Toshiba Electronics Europe has recently unveiled the TB67H482FNG, a high-performance H-bridge driver designed specifically for brushed DC motors used in consumer and industrial applications. This innovative driver is capable of handling voltages up to 50V and currents up to 5A, making it ideal for a wide range of applications that require large, high torque motors. Industries such as air conditioning, printing, robotics, and factory automation can benefit from the energy-saving features and simplified integration offered by this driver.

One of the key advantages of the TB67H482FNG is its ability to provide constant current control in a single package, resulting in enhanced voltage and current capabilities while consuming minimal power in sleep mode. By eliminating the need for external charge pump capacitors, manufacturers can streamline their design processes, save valuable board space, and reduce component count. Additionally, the built-in regulator enables the motor to be efficiently driven by a single VM power supply, further enhancing the overall efficiency of the system.

Controlled through a PHASE/ENABLE input interface, the TB67H482FNG features five torque setting input pins that allow for precise adjustment of the motor current across 32 levels. With a low on-resistance of 0.2Ω (typical) for both high-side and low-side outputs, this driver ensures efficient power delivery even under demanding conditions. Its wide operational voltage range of 8.2V to 44V caters to diverse motor power supply requirements, while the ultra-low sleep mode current consumption of less than 1μA maximizes energy efficiency.

In terms of safety and reliability, the TB67H482FNG is equipped with comprehensive error detection features, including overcurrent protection, thermal shutdown, under-voltage lockout, and error detection flag output. These safeguards not only ensure the smooth operation of the system but also provide essential protection for both the driver and the connected motor. Packaged in a compact HTSSOP28 form factor measuring just 6.4mm × 9.7mm, this driver offers a versatile and space-efficient solution for various motor-driven applications.

Building on its commitment to delivering cutting-edge motor control solutions, Toshiba Electronics Europe has expanded its portfolio with the introduction of the TB67H482FNG H-bridge driver. This latest addition complements the company's existing range of single-channel drivers, which support voltages from 4.5V to 50V and currents up to 3.5A. By offering a diverse selection of drivers with varying specifications, Toshiba aims to cater to the evolving needs of the consumer and industrial markets, empowering designers to create innovative and efficient motor control systems.
