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.

Features

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"x 1.0")Weight: 3.1 g¹
Exposed solderable ground pad below the driver IC on the bottom of the PCB

Included hardware

This product ships with all surface-mount components—including the TB9051FTG driver IC—installed as shown in the product picture. However, soldering is required for assembly of the included through-hole parts: one 1x17-pin breakaway 0.1" male header and two 2-pin, 3.5 mm terminal blocks (for board power and motor outputs).

General specifications

Motor driver: TB9051FTG
Motor channels: 1
Minimum operating voltage: 4.5 V. Operation from 4.5 V to 8 V reduces maximum current output.
Maximum operating voltage: 28 V. Transient operation (< 500 ms) up to 40 V.
Peak output current per channel: 5 A
Continuous output current: 2.6 A. Typical results at room temperature with VIN > 8 V and 90% duty cycle. Operation from 4.5 V to 8 V reduces maximum current output.
Current sense: 0.5 V/A
Maximum PWM frequency: 20 kHz
Reverse voltage protection: Y. On motor voltage only; logic voltage does not have reverse protection.
