H-bridge motor driver released for high-torque applications

Toshiba Electronics Europe GmbH has released the TB67H482FNG, an advanced motor driver designed to improve motor control in consumer and industrial applications. Optimised for the efficient drive of large brushed DC motors, this driver is excellent for high-torque equipment such as air conditioning systems, printers, scanners, office automation, motorised furniture, robotics, and factory automation. With robust voltage and current capabilities and ultra-low sleep mode power consumption, the device delivers an efficient and reliable solution for motor control, supplying simplified design integration for manufacturers and improved performance and energy savings for end-users.

The device is a constant-current single H-bridge driver featuring a motor output voltage rating of up to 50V and an output current rating of up to 5A. It is controlled by a PHASE/ENABLE input interface. Five torque setting input pins permit the motor current to be set to one of 32 levels. The device supports motor power supply voltages operational range from 8.2V to 44V and consumes less than 1μA (max.) in sleep mode. Motor output on-resistance (RDS(ON)) is only 0.2-Ohm (typ.) for high-side and low-side (at 24V when a 2A output current is applied).

The motor driver eradicates the necessity for external charge pump capacitors, saving board space and lowering component count. The built-in regulator permits the motor to be driven by a single VM power supply.

Equipped with comprehensive error detection features, including overcurrent detection, thermal shutdown, under voltage lockout and error detection flag output, the TB67H482FNG provides reliable operation and system protection. It is housed in a HTSSOP28 package measuring 6.4mm × 9.7mm, offering a compact and flexible solution for various motor-driven applications.
