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.

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
