The TB9051FTG is a single channel H-Bridge that supports both VBAT and VCC power supplies. In addition to forward, reverse and brake functions, it is also capable of PWM control, current limit control and usable for high-side current monitoring, diagnosis output and power on reset circuitry. The device is available in a 6 × 6mm P-QFN28 package, and is suited for small mounting boards.
Featuring an operational voltage range of VBAT=4.5 to 28V and VCC=4.5 to 5.5V and an on-resistance of 0.34O, the TB9051FTG applies DMOS transistors as driver circuits. The IC also uses various built-in failure detection features for functional safety. These include over current, over heat, low voltage and high voltage detection circuits.
