TB9051FTG Single Brushed DC Motor Driver Carrier

This breakout board makes it easy to use Toshiba’s TB9051FTG brushed DC motor driver. It has a wide operating voltage range of 4.5 V to 28 V and can deliver a continuous 2.6 A. A fixed current chopping threshold allows the TB9051 to limit the peak motor current, and it features built-in protection against under-voltage, over-current, and over-temperature conditions; our carrier board also adds reverse-voltage protection.


The TB9051FTG from Toshiba is an H-bridge motor driver IC that can be used for bidirectional control of a single brushed DC motor at 4.5 V to 28 V. It can supply up to about 2.6 A continuously, and it can deliver peak currents up to 5 A (typical) for a few seconds. The TB9051FTG is a great IC, but its small surface-mount package makes it difficult for the typical student or hobbyist to use; our breakout board makes it easy to use with standard solderless breadboards and 0.1″ perfboards. The board ships populated with SMD components, including the TB9051FTG and a reverse battery protection circuit.


  • Single-channel H-bridge motor driver
  • Motor supply voltage: 4.5 V to 28 V
  • Output current: up to 2.6 A continuous (5 A peak)
  • Automatic current chopping feature helps prevent overheating by gracefully reducing power rather than abruptly shutting down
  • Under-voltage lockout and protection against over-current/short-circuit and over-temperature
  • Carrier board adds reverse-voltage protection
  • Active-low error output indicates over-current, over-temperature, under-voltage, or VCC over-voltage condition
  • Compact size (1.0″ × 1.0″)
  • Exposed solderable ground pad below the driver IC on the bottom of the PCB
