Pololu TB9051FTG Single Brushed DC Motor Driver Carrier

Artikelnummer: PO2997

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.

Overview

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"× 1.0")
  • 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 1×17-pin breakaway 0.1" male header and two 2-pin, 3.5 mm terminal blocks (for board power and motor outputs).

The 0.1" male header can be broken or cut into smaller pieces as desired and soldered into the smaller through-holes. These headers are compatible with solderless breadboards, 0.1" female connectors, and our premium and pre-crimped jumper wires. The terminal blocks can be soldered into the larger holes to allow for convenient temporary connections of unterminated power and motor wires (see our short video on terminal block installation). You can also solder your motor leads and other connections directly to the board for the most compact installation.

Other PCB markings: 0J11154

Notes:

1 Without included hardware.
2 Operation from 4.5 V to 8 V reduces maximum current output.
3 The device is protected for transients up to 40 V.

This product can get hot enough to burn you long before the chip overheats. Take care when handling this product and other components connected to it.
